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…
ZTF J021804.16+071152.93: a dead cataclysmic variable and potential solution to the missing period bouncers
S. G. Parsons, A. J. Brown, S. L. Casewell +22
It is predicted that half or more of all cataclysmic variables (CVs) should have evolved past the period minimum and now exist as so-called "period bouncers" where a white dwarf sh…
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…
WRAP: A Tool for Efficient Cross-Identification of Proper Motion Objects Spanning Multiple Surveys
Hunter Brooks, J. Davy Kirkpatrick, Dan Caselden +11
We introduce the Wide-field Retrieval of Astrodata Program (WRAP), a tool created to aid astronomers in gathering photometric and astrometric data for point sources that may confus…
Long-term 4.6m Variability in Brown Dwarfs and a New Technique for Identifying Brown Dwarf Binary Candidates
Hunter Brooks, J. Davy Kirkpatrick, Aaron M. Meisner +11
Using a sample of 361 nearby brown dwarfs, we have searched for 4.6m variability indicative of large-scale rotational modulations or large-scale long-term changes on timescales…
The First Millimeter Detection of a Non-Accreting Ultracool Dwarf
P. K. G. Williams, S. L. Casewell, C. R. Stark +3
The well-studied M9 dwarf TVLM 513-46546 is a rapid rotator (P_rot ~ 2 hr) hosting a stable, dipolar magnetic field of ~3 kG surface strength. Here we report its detection with ALM…
Hubble Space Telescope Imaging and Spectroscopy of the Sirius-Like Triple Star System HD 217411
Jay B. Holberg, Sharah L. Casewell, Howard E. Bond +2
We present Hubble Space Telescope imaging and spectroscopy of HD 217411, a G3 V star associated with the extreme ultraviolet excess source (EUV 2RE J2300-07.0). This star is reveal…
The status and future of EUV astronomy
M. A. Barstow, S. L. Casewell, J. B. Holberg +1
The Extreme Ultraviolet wavelength range was one of the final windows to be opened up to astronomy. Nevertheless, it provides very important diagnostic tools for a range of astrono…
Low Mass Stars and Brown Dwarfs in Praesepe
D. E. A. Baker, R. F. Jameson, S. L. Casewell +3
Presented are the results of a large and deep optical-near-infrared multi-epoch survey of the Praesepe open star cluster using data from the UKIDSS Galactic Clusters Survey. Multip…
