    • Atmospheric Retrieval of L Dwarfs: Benchmarking Results and Characterizing the Young Planetary Mass Companion HD 106906 b in the Near-infrared 

      Adams, Arthur D.; Meyer, Michael R.; Howe, Alex R.; Burningham, Ben; Daemgen, Sebastian; Fortney, Jonathan; Line, Mike; Marley, Mark; Quanz, Sascha P.; Todorov, Kamen (2023-10-13)
      We present model constraints on the atmospheric structure of HD 106906 b, a planetary-mass companion orbiting at a ∼700 au projected separation around a 15 Myr old stellar binary, using the APOLLO retrieval code on spectral ...

    • 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 ...

    • 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 ...

    • Uniform Atmospheric Retrieval Analysis of Ultracool Dwarfs I : Characterizing Benchmarks, Gl570D and HD3651B 

      Line, Michael R.; Teske, Johanna; Burningham, Ben; Fortney, Jonathan; Marley, Mark (2015-07-10)
      Interpreting the spectra of brown dwarfs is key to determining the fundamental physical and chemical processes occurring in their atmospheres. Powerful Bayesian atmospheric retrieval tools have recently been applied to ...
