A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs

Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72

We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-res…

Clouds with a silicate lining: Using JWST spectra to probe atmospheric diversity in young AB Dor L dwarfs

M. B. Lam, J. M. Vos, G. Suárez +13

We present the first full JWST NIRSpec Prism and MIRI LRS 0.6 - 14 m (R ~ 100) spectra and analysis of five ~ 133 Myr L dwarf members of the AB Doradus moving group and one prob…

Identifying and Characterizing Very Low Mass Spectral Blend Binaries with Machine Learning Methods

Juan Diego Draxl Giannoni, Malina Desai, Adam J. Burgasser +5

We present an approach to identifying and characterizing unresolved, very low mass spectral blend binaries composed of late-M, L, and T dwarfs using machine learning methodologies.…

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 1.5 μm and 4.8 μm Photometry of Y Dwarfs

Loïc Albert, Sandy K. Leggett, Per Calissendorff +20

Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…

Thirteen New M Dwarf + T Dwarf Pairs Identified with WISE/NEOWISE

Federico Marocco, J. Davy Kirkpatrick, Adam C. Schneider +31

We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using WISE/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 project…
