Atmospheric circulation of exoplanets
地球与行星物理论评, 2023 To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is ...

A Uniform Search for Nearby Planetary Companions to Hot Jupiters in TESS Data Reveals Hot Jupiters Are Still Lonely [PDF]
Astronomical Journal, 2021 We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of the southern ecliptic hemisphere.

Slow Cooling and Fast Reinflation for Hot Jupiters [PDF]
, 2021 The unexpectedly large radii of hot Jupiters are a longstanding mystery whose solution will provide important insights into their interior physics.

The Continuing Search for Evidence of Tidal Orbital Decay of Hot Jupiters [PDF]
Astronomical Journal, 2020 Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot Jupiter for which orbital decay has been directly detected is WASP-12, for which transit-timing measurements spanning more than a decade have revealed that the ...

Modeling the High-resolution Emission Spectra of Clear and Cloudy Nontransiting Hot Jupiters [PDF]
Astrophysical Journal, 2021 The advent of high-resolution spectroscopy (R ≳ 25,000) as a method for characterization of exoplanet atmospheres has expanded our capability to study nontransiting planets, vastly increasing the number of planets accessible for observation.

On the Correlation between Hot Jupiters and Stellar Clustering: High-eccentricity Migration Induced by Stellar Flybys [PDF]
, 2021 A recent observational study suggests that the occurrence of hot Jupiters (HJs) around solar-type stars is correlated with stellar clustering. We study a new scenario for HJ formation, called “Flyby Induced High-e Migration,” that may help explain this ...

Sulfur chemistry in the atmospheres of warm and hot Jupiters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present and validate a new network of atmospheric thermochemical and photochemical sulfur reactions. We use a 1D chemical kinetics model to investigate these reactions as part of a broader HCNO chemical network in a series of hot and warm Jupiters ...

Inflation of migrated hot Jupiters
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The observed low densities of gas giant planets with a high equilibrium temperature (hot Jupiters) can be simulated in models when a fraction of the surface radiation is deposited deeper in the interior. Meanwhile, migration theories suggest that hot Jupiters formed further away from their host star and migrated inward.

THERMODYNAMICS OF ATMOSPHERIC CIRCULATION ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2009 Atmospheric circulation on tidally-locked exoplanets is driven by the absorption and reradiation of heat from the host star. They are natural heat engines, converting heat into mechanical energy. A steady state is possible only if there is a mechanism to dissipate mechanical energy, or if the redistribution of heat is so effective that the Carnot ...

Obliquity Tides on Hot Jupiters [PDF]
The Astrophysical Journal, 2005 Obliquity tides are a potentially important source of heat for extrasolar planets on close-in orbits. Although tidal dissipation will usually reduce the obliquity to zero, a nonzero obliquity can persist if the planet is in a Cassini state, a resonance between spin precession and orbital precession. Obliquity tides might be the cause of the anomalously
