Time-resolved JWST Retrieval Analysis of the Coldest Brown Dwarf: Temperature and Chemical Variations in WISE 0855-07

Harshil Kothari, Caroline V. Morley, Brittany E. Miles +12

WISE J0855-07 is the coldest known brown dwarf (estimated Teff~250 K), offering a rare opportunity to probe atmospheric physics in the temperature and mass regime that overlaps dir…

Water Cloud and Chemical Modulations in the Coldest Brown Dwarf

Brittany E. Miles, James Mang, Caroline V. Morley +24

We present high signal-to-noise, medium resolution (R ~ 1000), time-series JWST/NIRSpec spectra of WISE 0855 (265K), the coldest known brown dwarf. Medium resolution, time-series s…

The Diversity of Cold Worlds: Age and Characterization of the Exoplanet COCONUTS-2b

Rocio Kiman, Charles A. Beichman, Azul Ruiz Diaz +19

Studying cold brown dwarfs is key to understanding the diverse characteristics of cold giant exoplanets atmospheres. COCONUTS-2, is a wide binary system composed of a T9 brown dwar…

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…

JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System

Daniella C. Bardalez Gagliuffi, William O. Balmer, Laurent Pueyo +16

Most observed multi-planet systems are coplanar, in a dynamically "cold" configuration of concentric orbits like our own Solar System. With the James Webb Space Telescope (JWST) we…

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…

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…
