    • Cloud busting: enstatite and quartz clouds in the atmosphere of 2M2224-0158 

      Burningham, Ben; Faherty, Jacqueline K.; Gonzales, Eileen C.; Marley, Mark S.; Visscher, Channon; Lupu, Roxana; Gaarn, Joesphine; Bieger, Michelle Fabienne; Freedman, Richard; Saumon, Didier (2021-05-18)
      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, particle size distribution, scattering model, ...

    • A Comparative L-dwarf Sample Exploring the Interplay Between Atmospheric Assumptions and Data Properties 

      Gonzales, Eileen C.; Burningham, Ben; Faherty, Jacqueline K.; Lewis, Nikole K.; Visscher, Channon; Marley, Mark (2022-10-13)
      Comparisons of atmospheric retrievals can reveal powerful insights on the strengths and limitations of our data and modeling tools. In this paper, we examine a sample of 5 similar effective temperature (Teff) or spectral ...

    • The first retrieval of a substellar subdwarf: A cloud-free SDSS J125637.13-022452.4 

      Gonzales, Eileen C.; Burningham, Ben; Faherty, Jacqueline K.; Visscher, Channon; Marley, Mark S.; Lupu, Roxana; Freedman, Richard; Lewis, Nikole K. (2021-12-08)
      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 best fit by a cloud-free model with an ion ...

    • Longitudinally Resolved Spectral Retrieval (ReSpect) of WASP-43b 

      Cubillos, Patricio E.; Keating, Dylan; Cowan, Nicolas B.; Vos, Johanna M.; Burningham, Ben; Ygouf, Marie; Karalidi, Theodora; Zhou, Yifan; Gonzales, Eileen C. (2021-07-02)
      Thermal phase variations of short period planets indicate that they are not spherical cows: day-to-night temperature contrasts range from hundreds to thousands of degrees, rivaling their vertical temperature contrasts. ...

    • The puzzle of the formation of T8 dwarf Ross 458c 

      Gaarn, Josefine; Burningham, Ben; Faherty, Jacqueline K.; Visscher, Channon; Marley, Mark S.; Gonzales, Eileen C.; Calamari, Emily; Gagliuffi, Daniella Bardalez; Lupu, Roxana; Freedman, Richard (2023-06-01)
      At the lowest masses, the distinction between brown dwarfs and giant exoplanets is often blurred and literature classifications rarely reflect the deuterium burning boundary. Atmospheric characterization may reveal the ...
