    • An Atmospheric Retrieval of the Brown Dwarf Gliese 229B 

      Calamari, Emily; Faherty, Jacqueline K.; Burningham, Ben; Gonzales, Eileen; Bardalez-Gagliuffi, Daniella; Vos, Johanna M.; Gemma, Marina; Whiteford, Niall; Gaarn, Josefine (2022-12-01)
      We present results from an atmospheric retrieval analysis of Gl 229B using the Brewster retrieval code. We find the best fit model to be cloud-free, consistent with the T dwarf retrieval work of Line et al.; Zalesky et al. ...

    • 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 SDSS J1416+1348AB 

      Gonzales, Eileen; Burningham, Ben; Faherty, Jackie; Cleary, Colleen; Visscher, Channon; Marley, Mark; Lupu, Roxana; Freedman, Richard (2020-12-10)
      We present the distance-calibrated spectral energy distribution (SED) of the d/sdL7 SDSS J14162408+1348263A (J1416A) and an updated SED for SDSS J14162408+1348263B (J1416B). We also present the first retrieval analysis of ...
