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…
Benchmark Brown Dwarfs as Chemical Laboratories: Linking System Bulk Properties to Atmospheric Retrievals
Viktória Kecskeméthy, Ben Burningham, Fei Wang +8
We present the first atmospheric retrieval analysis of two compositional benchmark mid-L dwarfs -- SDSSJ141659.78+500626.4 and GJ 499 C -- using the \textit{Brewster} retrieval fra…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123
JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…
Connecting JWST Silicate Cloud Observations to Exoplanet Cloud Microphysics with Nimbus
Sven Kiefer, Caroline V. Morley, Melanie Rowland
The unprecedented accuracy of JWST has led to the detection of silicate clouds in exoplanet atmospheres, allowing for the first time to probe cloud formation in extreme environment…
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…
A Deep Search for Exomoons Around WISE 0855 With JWST
Mikayla J. Wilson, Mary Anne Limbach, Andrew J. Skemer +11
JWST is collecting time-series observations of many free-floating planets (FFPs) to study their weather, but these light curves are the ideal datasets to search for exomoons that t…
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…
Discovery of the Second Y+Y Dwarf Binary System: CWISEP J193518.59-154620.3
Matthew De Furio, Jacqueline Kelly Faherty, Daniella C. Bardalez Gagliuffi +10
We present the discovery of a companion to the Y-dwarf, CWISEP J193518.59-154620.3, the second Y-Y dwarf binary detected to date. Y-dwarfs are the coldest known free-floating objec…
Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system
Kielan K. W. Hoch, Melanie Rowland, Simon Petrus +26
Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, w…
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…
Protosolar D-to-H abundance and one part-per-billion PH in the coldest brown dwarf
Melanie J. Rowland, Caroline V. Morley, Brittany E. Miles +24
The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (200 -- 400 K) giant exoplanets. We can therefore use their atmospheres as proxi…
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…
