    • Methane Emission From a Cool Brown Dwarf 

      Faherty, Jacqueline K.; Burningham, Ben; Gagné, Jonathan; Suárez, Genaro; Vos, Johanna M.; Merchan, Sherelyn Alejandro; Morley, Caroline V.; Rowland, Melanie; Lacy, Brianna; Kiman, Rocio; Caselden, Dan; Kirkpatrick, J. Davy; Meisner, Aaron; Schneider, Adam C.; Kuchner, Marc Jason; Bardalez-Gagliuffi, Daniella; Beichman, Charles A.; Eisenhardt, Peter; Gelino, Christopher R.; Gharib-Nezhad, Ehsan; Gonzales, Eileen; Marocco, Federico; Rothermich, Austin James; Whiteford, Niall (2024-04-18)
      Beyond our solar system, aurorae have been inferred from radio obser- vations of isolated brown dwarfs (e.g. [1]; [2]). Within our solar system, giant planets have auroral emission with signatures across the electromag- ...

    • Patchy Forsterite Clouds in the Atmospheres of Two Highly Variable Exoplanet Analogs 

      Vos, Johanna M.; Burningham, Ben; Faherty, Jacqueline K.; Alejandro, Sherelyn; Gonzales, Eileen; Calamari, Emily; Gagliuffi, Daniella Bardalez; Visscher, Channon; Tan, Xianyu; Morley, Caroline V.; Marley, Mark; Gemma, Marina E.; Whiteford, Niall; Gaarn, Josefine; Park, Grace (2023-02-01)
      We present an atmospheric retrieval analysis of a pair of highly variable, ∼200 Myr old, early T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J21392676+0220226 using the Brewster retrieval framework. ...

    • Retrieval of atmospheric properties of cloudy L dwarfs 

      Burningham, Ben; Marley, Mark S.; Line, Michael R.; Lupu, Roxana; Visscher, Channon; Morley, Caroline V.; Saumon, Didier; Freedman, Richard (2017-09-01)
      We present the first results from applying the spectral inversion technique in the cloudy L dwarf regime. Our new framework provides a flexible approach to modelling cloud opacity which can be built incrementally as the ...

    • Uniform Atmospheric Retrieval Analysis of Ultracool Dwarfs II : Properties of 11 T-dwarfs 

      Line, Michael R.; Marley, Mark S.; Liu, Michael C.; Burningham, Ben; Morley, Caroline V.; Hinkel, Natalie R.; Teske, Johanna; Fortney, Jonathan J.; Lupu, Roxana; Freedman, Richard (2017-10-20)
      Brown dwarf spectra are rich in information revealing of the chemical and physical processes operating in their atmospheres. We apply a recently developed atmospheric retrieval tool to an ensemble of late T-dwarf (600-800K) ...
