Convection modeling of pure-steam atmospheres
Xianyu Tan, Maxence Lefevre, Raymond Pierrehumbert
Condensable species are crucial in shaping planetary climate. A wide range of planetary climate systems involve understanding non-dilute condensable substances and their influence…
TOI-2109b: An Ultrahot Gas Giant on a 16 hr Orbit
Ian Wong, Avi Shporer, George Zhou +56
We report the discovery of an ultrahot Jupiter with an extremely short orbital period of days (16 hr). The plane…
HST/WFC3 Complete Phase-resolved Spectroscopy of White Dwarf-Brown Dwarf Binaries WD 0137 and EPIC 2122
Yifan Zhou, Dániel Apai, Xianyu Tan +7
Brown dwarfs in close-in orbits around white dwarfs offer an excellent opportunity to investigate properties of fast-rotating, tidally-locked, and highly-irradiated atmospheres. We…
Mapping the pressure-dependent day-night temperature contrast of a strongly irradiated atmosphere with HST spectroscopic phase curve
Ben W. P. Lew, Dániel Apai, Yifan Zhou +6
Many brown dwarfs are on ultra-short period and tidally-locked orbits around white dwarf hosts. Because of these small orbital separations, the brown dwarfs are irradiated at level…
Modeling Polarization Signals from Cloudy Brown Dwarfs: Luhman 16 A and B in Three Dimensions
Sagnick Mukherjee, Jonathan J. Fortney, Rebecca Jensen-Clem +3
The detection of disk-integrated polarization from Luhman 16A and B in H-band, and subsequent modeling, has been interpreted in the framework of zonal cloud bands on these bodies.…
Simulating gas giant exoplanet atmospheres with Exo-FMS: Comparing semi-grey, picket fence and correlated-k radiative-transfer schemes
Elspeth K. H. Lee, Vivien Parmentier, Mark Hammond +5
Radiative-transfer (RT) is a fundamental part of modelling exoplanet atmospheres with general circulation models (GCMs). An accurate RT scheme is required for estimates of the atmo…
Atmospheric circulation of brown dwarfs and directly imaged exoplanets driven by cloud radiative feedback: global and equatorial dynamics
Xianyu Tan, Adam P. Showman
Brown dwarfs and directly imaged exoplanets exhibit observational evidence for active atmospheric circulation, raising critical questions about mechanisms driving the circulation,…
