An Atmospheric Retrieval of the Brown Dwarf Gliese 229B
(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. ...
A Comparative L-dwarf Sample Exploring the Interplay Between Atmospheric Assumptions and Data Properties
(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 ...
The first retrieval of a substellar subdwarf: A cloud-free SDSS J125637.13-022452.4
(2021-12-08)
We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13-022452.4 (SDSS J1256-0224), using the Brewster retrieval code base. We find SDSS J1256-0224 is best fit by a cloud-free model with an ion ...
Cloud busting: enstatite and quartz clouds in the atmosphere of 2M2224-0158
(2021-05-18)
We present the most detailed data-driven exploration of cloud opacity in a substellar object to-date. We have tested over 60 combinations of cloud composition and structure, particle size distribution, scattering model, ...
