The Sonora Substellar Atmosphere Models. VII. Flame Skimmer: Cloud-free Atmospheric and Evolutionary Models for the Coldest Substellar Objects
James Mang, Yayaati Chachan, Caroline V. Morley +7
JWST has provided unprecedented access to ultra-cool brown dwarfs and has pushed the boundaries of directly imaging temperate giant planets. As we continue to push toward detecting…
The Sonora Substellar Atmosphere Models. IV. Elf Owl: Atmospheric Mixing and Chemical Disequilibrium with Varying Metallicity and C/O Ratios
Sagnick Mukherjee, Jonathan J. Fortney, Caroline V. Morley +7
Disequilibrium chemistry due to vertical mixing in the atmospheres of many brown dwarfs and giant exoplanets is well-established. Atmosphere models for these objects typically para…
The impact of spectral line wing cut-off: Recommended standard method with application to MAESTRO opacity database
Ehsan, Gharib-Nezhad, Natasha E. Batalha +8
When computing cross-sections from a line list, the result depends not only on the line strength, but also the line shape, pressure-broadening parameters, and line wing cut-off (i.…
A unique hot Jupiter spectral sequence with evidence for compositional diversity
Megan Mansfield, Michael R. Line, Jacob L. Bean +11
The emergent spectra of close-in, giant exoplanets ("hot Jupiters") are expected to be distinct from those of self-luminous objects with similar effective temperatures because hot…
Decomposing the Iron Cross-Correlation Signal of the Ultra-Hot Jupiter WASP-76b in Transmission using 3D Monte-Carlo Radiative Transfer
Joost P. Wardenier, Vivien Parmentier, Elspeth K. H. Lee +2
Ultra-hot Jupiters are tidally locked gas giants with dayside temperatures high enough to dissociate hydrogen and other molecules. Their atmospheres are vastly non-uniform in terms…
EXOPLINES: Molecular Absorption Cross-Section Database for Brown Dwarf and Giant Exoplanet Atmospheres
Ehsan Gharib-Nezhad, Aishwarya R. Iyer, Michael R. Line +3
Stellar, substellar, and planetary atmosphere models are all highly sensitive to the input opacities. Generational differences between various state-of-the-art stellar/planetary mo…
H2-Induced Pressure Broadening and Pressure Shift in the P-Branch of the v3 Band of CH4 from 300 to 700 K
Ehsan Gharib-Nezhad, Alan N. Heays, Hans A. Bechtel +1
For accurate modelling of observations of exoplanet atmospheres, quantification of the pressure broadening of infrared absorption lines for and by a variety of gases at elevated te…
The Need for Laboratory Measurements and Ab Initio Studies to Aid Understanding of Exoplanetary Atmospheres
Jonathan J. Fortney, Tyler D. Robinson, Shawn Domagal-Goldman +85
We are now on a clear trajectory for improvements in exoplanet observations that will revolutionize our ability to characterize their atmospheric structure, composition, and circul…
The Influence of H2O Pressure Broadening in High Metallicity Exoplanet Atmospheres
Ehsan Gharib-Nezhad, Michael R. Line
Planet formation models suggest broad compositional diversity in the sub-Neptune/super-Earth regime, with a high likelihood for large atmospheric metal content (> 100 x Solar). Wit…
