New Ultracool Companions to Nearby White Dwarfs
Alexia Bravo, Adam C. Schneider, Sarah Casewell +15
We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and…
New Cold Subdwarf Discoveries from Backyard Worlds and a Metallicity Classification System for T Subdwarfs
Adam J. Burgasser, Adam C. Schneider, Aaron M. Meisner +36
We report the results of a spectroscopic survey of candidate T subdwarfs identified by the Backyard Worlds: Planet 9 program. Near-infrared spectra of 31 sources with red co…
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…
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…
Ancient nova shells of RX Pup indicate evolution of mass transfer rate
Krystian Ilkiewicz, Joanna Mikolajewska, Michael M. Shara +1
RX Pup is a symbiotic binary which experienced a nova outburst in the 1970's. Here we report a discovery of a ~1300 year old nova shell around the system and a possible detection o…
Discovery of a Hypervelocity L Subdwarf at the Star/Brown Dwarf Mass Limit
Adam J. Burgasser, Roman Gerasimov, Kyle Kremer +18
We report the discovery of a high velocity, very low-mass star or brown dwarf whose kinematics suggest it is unbound to the Milky Way. CWISE J124909.08+362116.0 was identified by c…
