Metal-poor Brown Dwarf Kinematics from JWST NIRSpec Spectroscopy
Chih-Chun Hsu, Christopher A. Theissen, Adam J. Burgasser +14
Galactic archaeology relies on stellar kinematics and chemical abundances to identify various stellar populations and associations. With JWST, Galactic archaeology of ancient metal…
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…
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…
89 New Ultracool Dwarf Co-Moving Companions Identified With The Backyard Worlds: Planet 9 Citizen Science Project
Austin Rothermich, Jacqueline K. Faherty, Daniella Bardalez-Gagliuffi +43
We report the identification of 89 new systems containing ultracool dwarf companions to main sequence stars and white dwarfs, using the citizen science project Backyard Worlds: Pla…
High-Precision Atmospheric Constraints for a Cool T Dwarf from JWST Spectroscopy
Callie E. Hood, Sagnick Mukherjee, Jonathan J. Fortney +12
We present observations of the T8 dwarf 2MASS 0415-0935 with JWST's NIRSpec spectrograph using the G395H grating ( 2.87 - 5.14 m). We perform the first atmospheric retriev…
The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
