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…
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…
A search for late-type brown dwarfs in the Euclid Quick Data Release 1
Frank Kiwy, J. Davy Kirkpatrick, Adam C. Schneider +9
We present the identification and characterization of 15 mid-to-late T dwarf candidates in the Euclid Quick Release 1 (Q1) dataset, based on a combined photometric and spectroscopi…
High Proper Motion Discoveries from the UKIRT Hemisphere Survey
Wings Zhang, Adam C. Schneider, Thomas P. Bickle +31
We used the third data release of the UKIRT Hemisphere Survey to locate previously unrecognized high proper motion objects. We identify a total of 127 new discoveries with total pr…
Disentangling the Effects of Temperature, Clouds, and Gravity on K I doublet in L dwarfs
Alexandra J. Baldelli, Genaro Suárez, Kelle L. Cruz +2
We investigate the effects of surface gravity, effective temperature, and cloudiness on the potassium doublet (\ion{K}{1}) at 1.17 μm in brown dwarf spectra. Using pseudo-Voigt pr…
Unveiling the Infrared Excess of SIPS J2045-6332: Evidence for a Young Stellar Object with Potential Low-Mass Companion
Michiharu Hyogo, Thomas P. Bickle, Joseph R. Biggs +20
The Disk Detective project, a citizen science initiative, aims to identify circumstellar discs around stars by detecting objects with infrared (IR) excess using data from the Wide-…
