    • 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. ...

    • 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. ...

    • 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. ...
