SMDET-1: a Nearby Y Dwarf Candidate
Aaron M. Meisner, Dan Caselden, Federico Marocco +11
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…
Discovery of 118 New Ultracool Dwarf Candidates Using Machine Learning Techniques
Hunter Brooks, Dan Caselden, J. Davy Kirkpatrick +44
We present the discovery of 118 new ultracool dwarf candidates, discovered using a new machine learning tool, named \texttt{SMDET}, applied to time series images from the Wide-fiel…
The Gaia Ultracool Dwarf Sample -- V: The Ultracool Dwarf Companion catalogue
Sayan Baig, R. L. Smart, Hugh R. A. Jones +4
We present the Ultracool Dwarf Companion Catalogue of 278 multiple systems, 32 of which are newly discovered, each with at least one spectroscopically confirmed Ultracool Dwarf, wi…
Revisiting physical parameters of the benchmark brown dwarf LHS 6343 C through a HST/WFC3 secondary eclipse observation
William Frost, Loïc Albert, René Doyon +7
The LHS 6343 system consists of a resolved M-dwarf binary with an evolved, negligibly irradiated brown dwarf, LHS 6343 C, orbiting the primary star. Such brown dwarf eclipsing bina…
NIRPS first light and early science: breaking the 1 m/s RV precision barrier at infrared wavelengths
Étienne Artigau, François Bouchy, René Doyon +111
The Near-InfraRed Planet Searcher or NIRPS is a precision radial velocity spectrograph developed through collaborative efforts among laboratories in Switzerland, Canada, Brazil, Fr…
Discovery of the Remarkably Red L/T Transition Object VHS J183135.58-551355.9
Thomas P. Bickle, Adam C. Schneider, Jonathan Gagné +15
We present the discovery of VHS J183135.58551355.9 (hereafter VHS J18315513), an L/T transition dwarf identified as a result of its unusually red near-infrared colors ($J-K_{…
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…
