    • 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 observations of isolated brown dwarfs 1,2. Within our Solar System, giant planets have auroral emission with signatures across the electromagnetic spectrum ...

    • 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 ...

    • Retrieving Young Cloudy L-Dwarfs : A Nearby Planetary-Mass Companion BD+60 1417B and Its Isolated Red Twin W0047 

      Phillips, Caprice L.; Faherty, Jacqueline K.; Burningham, Ben; Vos, Johanna M.; Gonzales, Eileen; Griffith, Emily J.; Merchan, Sherelyn Alejandro; Calamari, Emily; Visscher, Channon; Morley, Caroline V.; Whiteford, Niall; Gaarn, Josefine; Ilyin, Ilya; Strassmeier, Klaus (2024-09-05)
      We present an atmospheric retrieval analysis on a set of young, cloudy, red L-dwarfs -- CWISER J124332.12+600126.2 and WISEP J004701.06+680352.1 -- using the \textit{Brewster} retrieval framework. We also present the first ...

    • 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) ...
