SMDET-1: a Nearby Y Dwarf Candidate
The Backyard Worlds, :, Planet 9 Collaboration +15
We present the discovery of SMDET-1, a red, fast-moving object ("/yr) identified in time-resolved unWISE coadds using a pixel-level deep learning methodology called S…
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-re…
Spectroscopic Characterization of WD J000801.25-350450 and its Two Co-Moving Companions
Peter A. JaÅowiczor, Thomas P. Bickle, J. Davy Kirkpatrick +18
We present new spectroscopic data for Gaia DR3 2309499817384726016 (WD0008-350A) and its two wide, co-moving, low-mass companions. We confirm the white dwarf is a hydrogen-rich DA,…
Three Thousand Motion-Confirmed L and T Dwarf Candidates from the Backyard Worlds:~Planet 9 Citizen Science Project
Adam C. Schneider, Marc J. Kuchner, Jacqueline K. Faherty +73
The Backyard Worlds: Planet 9 citizen science project uses data from the Wide-field Infrared Survey Explorer to detect infrared objects with significant motion. In this work, we pr…
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 pro…
The Montreal Open Clusters and Associations (MOCA) Database: A Census of Nearby Associations, Open Clusters, and Young Substellar Objects within 500 pc of the Sun
Jonathan Gagné, Leslie Moranta, Jacqueline K. Faherty +10
We present the Montreal Open Clusters and Associations database (MOCAdb), a public MySQL database with a Python interface. MOCAdb provides a census of memberships for 10259 associa…
