“Hot Jupiters” aren't very friendly. Few of the giant planets have nearby companion planets. That could mean that the hot Jupiters have kicked other planets away. Hot Jupiters were the first planets discovered in other star systems. They're big, heavy balls of gas, like Jupiter, the giant of our own solar system. But while Jupiter is far from the Sun, hot Jupiters are quite close in, so they're heated to hundreds or thousands of degrees. Such planets can't form that close to a star — it's just too hot. They must have been born farther out, then moved inward. The question is whether that's a gentle process, allowing the Jupiter to co-exist with other planets, or a more violent one that boots the other planets out of its way. And so far, the “violent” scenario has been the most likely, because astronomers have found few close companion planets. But in a recent study, about one in eight hot Jupiters did have a nearby companion. Those Jupiter-like worlds must have migrated inward in the gentler process, sparing their sibling worlds. And warm Jupiters — those that are a little farther out — were more hospitable: about two-thirds had close companions. So there may be more than one way for a Jupiter to fall toward its parent star. Our own Jupiter teams up with the Moon the next few nights. It looks like a brilliant star. It's well to the lower left of the Moon tonight, but will huddle much closer tomorrow night.

Making hot Jupiters in stellar clusters: the importance of binary exchange

Making hot Jupiters in stellar clusters: the importance of binary exchange by Daohai Li et al. on Wednesday 30 November It has been suggested that the occurrence rate of hot Jupiters (HJs) in open clusters might reach several per cent, significantly higher than that of the field ($sim$ a per cent). In a stellar cluster, when a planetary system scatters with a stellar binary, it may acquire a companion star which may excite large amplitude von Zeipel-Lidov-Kozai oscillations in the planet's orbital eccentricity, triggering high-eccentricity migration and the formation of an HJ. We quantify the efficiency of this mechanism by modelling the evolution of a gas giant around a solar mass star under the influence of successive scatterings with binary and single stars. We show that the chance that a planet $in(1,10)$ au becomes an HJ in a Gyr in a cluster of stellar density $n_*=50$ pc$^{-3}$ and binary fraction $f_mathrm{bin}=0.5$ is about 2% and an additional 4% are forced by the companion star into collision with or tidal disruption by the central host. An empirical fit shows that the total percentage of those outcomes asymptotically reaches an upper limit determined solely by $f_mathrm{bin}$ (e.g., $10%$ at $f_mathrm{bin}=0.3$ and 18% at $f_mathrm{bin}=1$) on a timescale inversely proportional to $n_*$ ($sim$ Gyr for $n_*sim100$ pc$^{-3}$). The ratio of collisions to tidal disruptions is roughly a few, and depends on the tidal model. Therefore, if the giant planet occurrence rate is 10~%, our mechanism implies an HJ occurrence rate of a few times 0.1~% in a Gyr and can thus explain a substantial fraction of the observed rate. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16015v1

We complement these data with literature information on stellar pulsations and Spitzer/Infrared Array Camera and Transiting Exoplanet Survey Satellite eclipse depths of this target to obtain a broadband thermal emission spectrum. Our extracted spectrum exhibits a clear turnoff at 1.4$mu$m. This points to H$^{-}$ bound-free opacities shaping the spectrum. To interpret the spectrum, we perform grid retrievals of self-consistent 1D equilibrium chemistry forward models, varying the composition and energy budget. The model with solar metallicity and C/O ratio provides a poor fit because the H$^{-}$ signal is stronger than expected, requiring an excess of electrons. This pushes our retrievals toward high atmospheric metallicities ($[M/H]=1.98^{+0.19}_{-0.21}$) and a C/O ratio that is subsolar by 2.4$sigma$. We question the viability of forming such a high-metallicity planet, and therefore provide other scenarios to increase the electron density in this atmosphere. We also look at an alternative model in which we quench TiO and VO. This fit results in an atmosphere with a slightly subsolar metallicity and subsolar C/O ratio ($[M/H]=-0.22^{+0.17}_{-0.13}$, log(C/O)$=-0.34^{+0.19}_{-0.34}$). However, the required TiO abundances are disputed by recent high-resolution measurements of the same planet. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.10297v1

Occurrence rate of hot Jupiters around early-type M dwarfs based on TESS data by Tianjun Gan et al. on Monday 17 October We present an estimate of the occurrence rate of hot Jupiters ($7 R_{oplus}leq R_{p}leq 2 R_{J}$, $0.8 leq P_{b}leq 10$ days) around early-type M dwarfs based on stars observed by TESS during its Primary Mission. We adopt stellar parameters from the TESS Input Catalog, and construct a sample of 60,819 M dwarfs with $10.5 leq T_{rm mag}leq 13.5$, effective temperature $2900 leq T_{rm eff}leq 4000 K$ and stellar mass $0.45leq M_{ast}leq 0.65 M_{odot}$. We conduct a uninformed transit search using a detection pipeline based on the box least square search and characterize the searching completeness through an injection and recovery experiment. We combine a series of vetting steps including light centroid measurement, odd/even and secondary eclipse analysis, rotation and transit period synchronization tests as well as inspecting the ground-based photometric, spectroscopic and imaging observations. Finally, we find a total of nine planet candidates, all of which are known TESS objects of interest. We obtain an occurrence rate of $0.27pm0.09%$ for hot Jupiters around early-type M dwarfs that satisfy our selection criteria. Compared with previous studies, the occurrence rate of hot Jupiters around early-type M dwarfs is smaller than all measurements for FGK stars, although they are consistent within 1--2$sigma$. Combining results from transit, radial velocity and microlensing surveys, we find that hot Jupiters around early-type M dwarfs possibly show a steeper decrease in occurrence rate per logarithmic semi-major axis bin (${{rm d}N}/{rm d}log_{10} a$) when compared with FGK stars. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08313v1

Atmospheric heat redistribution effect on Emission spectra of Hot-Jupiters

Atmospheric heat redistribution effect on Emission spectra of Hot-Jupiters by Soumya Sengupta et al. on Monday 17 October Hot Jupiters are the most studied and easily detectable exoplanets for transit observations.However, the correlation between the atmospheric flow and the emission spectra of such planets is still not understood. Due to huge day-night temperature contrast in hot Jupiter, the thermal redistribution through atmospheric circulation has a significant impact on the vertical temperature-pressure structure and on the emission spectra. In the present work, we aim to study the variation of the temperature-pressure profiles and the emission spectra of such planets due to different amounts of atmospheric heat redistribution. For this purpose, we first derive an analytical relation between the heat redistribution parameter f and the emitted flux from the uppermost atmospheric layers of hot Jupiter. We adopt the three possible values of f under isotropic approximation as 1/4, 1/2, and 2/3 for full-redistribution, semi-redistribution and no-redistribution cases respectively and calculate the corresponding temperature-pressure profiles and the emission spectra. Next, we model the emission spectra for different values of f by numerically solving the radiative transfer equations using the discrete space theory formalism. We demonstrate that the atmospheric temperature-pressure profiles and the emission spectra both are susceptible to the values of the heat redistribution function. A reduction in the heat redistribution yields a thermal inversion in the temperature-pressure profiles and hence increases the amount of emission flux. Finally, we revisits the hot Jupiter XO-1b temperature-pressure profile degeneracy case and show that a non-inversion temperature-pressure profile best explains this observed planetary dayside emission spectra. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08755v1

Occurrence rate of hot Jupiters around early-type M dwarfs based on TESS data by Tianjun Gan et al. on Monday 17 October We present an estimate of the occurrence rate of hot Jupiters ($7 R_{oplus}leq R_{p}leq 2 R_{J}$, $0.8 leq P_{b}leq 10$ days) around early-type M dwarfs based on stars observed by TESS during its Primary Mission. We adopt stellar parameters from the TESS Input Catalog, and construct a sample of 60,819 M dwarfs with $10.5 leq T_{rm mag}leq 13.5$, effective temperature $2900 leq T_{rm eff}leq 4000 K$ and stellar mass $0.45leq M_{ast}leq 0.65 M_{odot}$. We conduct a uninformed transit search using a detection pipeline based on the box least square search and characterize the searching completeness through an injection and recovery experiment. We combine a series of vetting steps including light centroid measurement, odd/even and secondary eclipse analysis, rotation and transit period synchronization tests as well as inspecting the ground-based photometric, spectroscopic and imaging observations. Finally, we find a total of nine planet candidates, all of which are known TESS objects of interest. We obtain an occurrence rate of $0.27pm0.09%$ for hot Jupiters around early-type M dwarfs that satisfy our selection criteria. Compared with previous studies, the occurrence rate of hot Jupiters around early-type M dwarfs is smaller than all measurements for FGK stars, although they are consistent within 1--2$sigma$. Combining results from transit, radial velocity and microlensing surveys, we find that hot Jupiters around early-type M dwarfs possibly show a steeper decrease in occurrence rate per logarithmic semi-major axis bin (${{rm d}N}/{rm d}log_{10} a$) when compared with FGK stars. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08313v1

Atmospheric heat redistribution effect on Emission spectra of Hot-Jupiters by Soumya Sengupta et al. on Monday 17 October Hot Jupiters are the most studied and easily detectable exoplanets for transit observations.However, the correlation between the atmospheric flow and the emission spectra of such planets is still not understood. Due to huge day-night temperature contrast in hot Jupiter, the thermal redistribution through atmospheric circulation has a significant impact on the vertical temperature-pressure structure and on the emission spectra. In the present work, we aim to study the variation of the temperature-pressure profiles and the emission spectra of such planets due to different amounts of atmospheric heat redistribution. For this purpose, we first derive an analytical relation between the heat redistribution parameter f and the emitted flux from the uppermost atmospheric layers of hot Jupiter. We adopt the three possible values of f under isotropic approximation as 1/4, 1/2, and 2/3 for full-redistribution, semi-redistribution and no-redistribution cases respectively and calculate the corresponding temperature-pressure profiles and the emission spectra. Next, we model the emission spectra for different values of f by numerically solving the radiative transfer equations using the discrete space theory formalism. We demonstrate that the atmospheric temperature-pressure profiles and the emission spectra both are susceptible to the values of the heat redistribution function. A reduction in the heat redistribution yields a thermal inversion in the temperature-pressure profiles and hence increases the amount of emission flux. Finally, we revisits the hot Jupiter XO-1b temperature-pressure profile degeneracy case and show that a non-inversion temperature-pressure profile best explains this observed planetary dayside emission spectra. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08755v1

Evidence of Long-Term Period Variations in the Exoplanet Transit Database ETD by Simone R. Hagey et al. on Thursday 22 September We analyze a large number of citizen science data and identify eight Hot Jupiter systems that show evidence for deviations from a constant orbital period: HAT-P-19 b, HAT-P-32 b, TrES-1 b, TrES-2 b, TrES-5 b, WASP-4 b, WASP-10 b, and WASP-12 b. The latter system is already well known to exhibit strong evidence for tidal orbital decay and serves as an important control for this study. Several other systems we identify have disputed period drifts in the literature, allowing the results here to serve as an independent analysis. The citizen science data are from the Exoplanet Transit Database (ETD), which is a global project established in 2008 by the Variable Star and Exoplanet Section of the Czech Astronomical Society. With over 400 planets and 12,000 contributed observations spanning 15 years, the ETD is brimming with potential for studying the long-term orbital evolution of close-in Hot Jupiters. We use our results to discuss prioritization of targets for follow up investigations, which will be necessary to confirm the period drifts and their causes. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.10752v1

Atmospheric characterization of the ultra-hot Jupiter WASP-33b: Detection of Ti and V emission lines and retrieval of a broadened line profile by D. Cont et al. on Thursday 22 September Ultra-hot Jupiters are highly irradiated gas giant exoplanets on close-in orbits around their host stars. We analyzed high-resolution spectra from CARMENES, HARPS-N, and ESPaDOnS taken over eight observation nights to study the emission spectrum of WASP-33b and draw conclusions about its atmosphere. By applying the cross-correlation technique, we detected the spectral signatures of Ti I, V I, and a tentative signal of Ti II for the first time via emission spectroscopy. These detections are an important finding because of the fundamental role of Ti- and V-bearing species in the planetary energy balance. Moreover, we assessed and confirm the presence of OH, Fe I, and Si I from previous studies. The spectral lines are all detected in emission, which unambiguously proves the presence of an inverted temperature profile in the planetary atmosphere. By performing retrievals on the emission lines of all the detected species, we determined a relatively weak atmospheric thermal inversion extending from approximately 3400 K to 4000 K. We infer a supersolar metallicity close to 1.5 dex in the planetary atmosphere, and find that its emission signature undergoes significant line broadening with a Gaussian FWHM of about 4.5 km/s. Also, we find that the atmospheric temperature profile retrieved at orbital phases far from the secondary eclipse is about 300 K to 700 K cooler than that measured close to the secondary eclipse, which is consistent with different day- and nightside temperatures. Moreover, retrievals performed on the emission lines of the individual chemical species lead to consistent results, which gives additional confidence to our retrieval method. Increasing the number of species included in the retrieval and expanding the set of retrieved atmospheric parameters will further advance our understanding of exoplanet atmospheres. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.10618v1

Detection of Paschen β absorption in the atmosphere of KELT-9 b: A new window into the atmospheres of ultra-hot Jupiters by A. Sánchez-López et al. on Tuesday 20 September Hydrogen and helium transmission signals trace the upper atmospheres of hot gas-giant exoplanets, where the incoming stellar extreme ultraviolet and X-ray fluxes are deposited. Further, for the hottest stars, the near-ultraviolet excitation of hydrogen in the Balmer continuum may play a dominant role in controlling the atmospheric temperature and driving photoevaporation. KELT-9 b is the archetypal example of such an environment as it is the hottest gas-giant exoplanet known to date (T$_{eq}$ $sim$ 4500 K) and orbits an A0V-type star. Studies of the upper atmosphere and escaping gas of this ultra-hot Jupiter have targeted the absorption in the Balmer series of hydrogen (n$_1$ = 2 $rightarrow$ n$_2$ $>$ 2). Unfortunately, the lowermost metastable helium state that causes the triplet absorption at 108.3 nm is not sufficiently populated for detection. Here, we present evidence of hydrogen absorption in the Paschen series in the transmission spectrum of KELT-9 b observed with CARMENES. Specifically, we focus on the strongest line covered by its NIR channel, Paschen-$beta$ at 1282.16 nm (n$_1$ = 3 $rightarrow$ n$_2$ = 5). The observed absorption shows a contrast of (0.53 $^{+0.12}_{-0.13}$)%, a blueshift of $-$14.8 $^{+3.5}_{-3.2}$ km/s, and a FWHM of 31.9$^{+11.8}_{-8.3}$ km/s. The observed blueshift in the absorption feature could be explained by day-to-night circulation within the gravitationally bound atmosphere or, alternatively, by Paschen-$beta$ absorption originating in a tail of escaping gas moving toward the observer as a result of extreme atmospheric evaporation. This detection opens a new window for investigating the atmospheres of ultra-hot Jupiters, providing additional constraints of their temperature structure, mass-loss rates, and dynamics for future modeling of their scorching atmospheres. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.01854v2
