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…
The Dyn-Atmo Survey: JWST/NIRSpec spectroscopy of dynamical benchmark GJ 758 B
Alexander Madurowicz, Emily Rickman, Daniella Bardalez Gagliuffi +22
We present new JWST/NIRSpec IFU high contrast spectroscopic observations of the brown dwarf companion GJ 758 B. Extensive radial velocity monitoring of the primary has enabled high…
The Dyn-Atmo Survey: High-contrast Imaging Spectroscopy of the Substellar Companion HD 13724 B with the JWST NIRSpec IFU
Kielan K. W. Hoch, Alex Madurowicz, Evert Nasedkin +22
We present the first spectral analysis from the JWST Cycle 3 GO Program #6362, the Dyn-Atmo Survey of dynamical-atmospheric benchmarks, characterizing the atmospheres of directly-i…
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…
Benchmark Brown Dwarf Systems I: Chemical Abundance Analysis of FGK Stars with Wide-Separation Brown Dwarf Companions Using PEPSI
Caprice L. Phillips, Megan Bedell, Catherine Manea +11
We present results from a spectroscopic survey of 32 FGK stars hosting brown dwarfs, using high-resolution optical spectra (R = 130,000 and 50,000) obtained with the PEPSI spectrog…
The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-Dependent Variability Driven by Multiple Mechanisms
Allison M. McCarthy, Johanna M. Vos, Philip S. Muirhead +17
Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate the…
Eight New Substellar Hyades Candidates from the UKIRT Hemisphere Survey
Adam C. Schneider, Michael C. Cushing, Robert A. Stiller +16
We have used the UKIRT Hemisphere Survey (UHS) combined with the UKIDSS Galactic Cluster Survey (GCS), the UKIDSS Galactic Plane Survey (GPS), and the CatWISE2020 catalog to search…
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…
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…
Predicting Cloud Conditions in Substellar Mass Objects Using Ultracool Dwarf Companions
Emily Calamari, Jacqueline K. Faherty, Channon Visscher +3
We present results from conducting a theoretical chemical analysis of a sample of benchmark companion brown dwarfs whose primary star is of type F, G or K. We summarize the entire…
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…
The puzzle of the formation of T8 dwarf Ross 458c
Josefine Gaarn, Ben Burningham, Jacqueline K. Faherty +7
At the lowest masses, the distinction between brown dwarfs and giant exoplanets is often blurred and literature classifications rarely reflect the deuterium burning boundary. Atmos…
Patchy Forsterite Clouds in the Atmospheres of Two Highly Variable Exoplanet Analogs
Johanna M. Vos, Ben Burningham, Jacqueline K. Faherty +12
We present an atmospheric retrieval analysis of a pair of highly variable, Myr old, early-T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J213926…
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…
