Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters

Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12

Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…

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 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…

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…

Discovery of the Remarkably Red L/T Transition Object VHS J183135.58-551355.9

Thomas P. Bickle, Adam C. Schneider, Jonathan Gagné +15

We present the discovery of VHS J183135.58551355.9 (hereafter VHS J18315513), an L/T transition dwarf identified as a result of its unusually red near-infrared colors ($J-K_{…

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…
