Sinking Silicates I: Characterizing the benchmark system containing the T0 brown dwarf CWISE J210640.16+250729.0 using JWST

Austin Rothermich, Jacqueline K. Faherty, Ben Burningham +16

In this study, we present the full (97.3\% complete) 0.8--12.5 m spectral energy distribution (SED) of an L/T transition object, CWISE J210640.16+250729.0 (CW2106), using the Ja…

Diversity of Cold Worlds: Predicted Near- to Mid-infrared Spectral Signatures of a Cold Brown Dwarf with Potential Auroral Heating

Genaro Suárez, Jacqueline K. Faherty, Ben Burningham +12

Recent JWST/NIRSpec observations have revealed strong methane emission at 3.326 microns in the 482 K brown dwarf CWISEP J193518.59154620.3 (W1935). Atmospheric modeling…

Diversity of Cold Worlds: A Near Complete Spectral Energy Distribution for 2MASS J04151954-0935066 using JWST

Sherelyn Alejandro Merchan, Jacqueline K. Faherty, Genaro Suárez +25

We present the a near complete spectral energy distribution (SED) for an extrasolar world: the T8 brown dwarf 2MASS~J041519540935066. Spanning from optical to mid-infrared (0.7-…

The JWST weather report from the nearest brown dwarfs II: Consistent variability mechanisms over 7 months revealed by 1-14 m NIRSpec + MIRI monitoring of WISE 1049AB

Xueqing Chen, Beth A. Biller, Xianyu Tan +22

We present a new epoch of JWST spectroscopic variability monitoring of the benchmark binary brown dwarf WISE 1049AB, the closest, brightest brown dwarfs known. Our 8-hour MIRI low…

The Diversity of Cold Worlds: a blended-light binary straddling the T/Y transition in brown dwarfs

Daniella C. Bardalez Gagliuffi, Jacqueline K. Faherty, Genaro Suarez +22

We present the first brown dwarf spectral binary characterized with JWST: WISE J014656.66+423410.0, the coldest blended-light brown dwarf binary straddling the T/Y transition. We o…

The JWST Weather Report from the Nearest Brown Dwarfs I: multi-period JWST NIRSpec + MIRI monitoring of the benchmark binary brown dwarf WISE 1049AB

Beth A. Biller, Johanna M. Vos, Yifan Zhou +22

We report results from 8 hours of JWST/MIRI LRS spectroscopic monitoring directly followed by 7 hours of JWST/NIRSpec prism spectroscopic monitoring of the benchmark binary brown d…

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

Caprice L. Phillips, Jacqueline K. Faherty, Ben Burningham +11

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} retr…

Methane Emission From a Cool Brown Dwarf

Jacqueline K. Faherty, Ben Burningham, Jonathan Gagné +21

Beyond our solar system, aurorae have been inferred from radio observations of isolated brown dwarfs (e.g. Hallinan et al. 2006; Kao et al. 2023). Within our solar system, giant pl…

An Atmospheric Retrieval of the Brown Dwarf Gliese 229B

Emily Calamari, Jacqueline K. Faherty, Ben Burningham +6

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 ret…
