The Sonora Substellar Atmosphere Models. II. Cholla: A Grid of Cloud-free, Solar Metallicity Models in Chemical Disequilibrium for the JWST Era
Theodora Karalidi, Mark Marley, Jonathan J. Fortney +5
Exoplanet and brown dwarf atmospheres commonly show signs of disequilibrium chemistry. In the James Webb Space Telescope era high resolution spectra of directly imaged exoplanets w…
The first retrieval of a substellar subdwarf: A cloud-free SDSS J125637.13-022452.4
Eileen C. Gonzales, Ben Burningham, Jacqueline K. Faherty +5
We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13-022452.4 (SDSS J1256-0224), using the Brewster retrieval code base. We find SDSS J1256-0224 is bes…
The Sonora Brown Dwarf Atmosphere and Evolution Models I. Model Description and Application to Cloudless Atmospheres in Rainout Chemical Equilibrium
Mark S. Marley, Didier Saumon, Channon Visscher +8
We present a new generation of substellar atmosphere and evolution models, appropriate for application to studies of L, T, and Y-type brown dwarfs and self-luminous extrasolar plan…
Detection and Bulk Properties of the HR 8799 Planets with High Resolution Spectroscopy
Jason J. Wang, Jean-Baptiste Ruffio, Evan Morris +49
Using the Keck Planet Imager and Characterizer (KPIC), we obtained high-resolution (R35,000) -band spectra of the four planets orbiting HR 8799. We clearly detected \water…
Following the Lithium: Tracing Li-bearing Molecules Across Age, Mass, and Gravity in Brown Dwarfs
Ehsan Gharib-Nezhad, Mark S. Marley, Natasha E. Batalha +3
Lithium is an important element for the understanding of ultracool dwarfs because it is lost to fusion at masses above . Hence, the presence or absence of atom…
Cloud busting: enstatite and quartz clouds in the atmosphere of 2M2224-0158
Ben Burningham, Jacqueline K. Faherty, Eileen C. Gonzales +7
We present the most detailed data-driven exploration of cloud opacity in a substellar object to-date. We have tested over 60 combinations of cloud composition and structure, partic…
