Spitzer + HST parallaxes of 13 late T and Y dwarfs
Federico Marocco, J. Davy Kirkpatrick, Richard L. Smart +13
We present astrometric measurements for 13 cold brown dwarfs in the solar neighborhood (d < 20pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) obse…
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…
The Rise and Fall of the King: The Correlation between FO Aquarii's Low States and the White Dwarf's Spindown
Colin Littlefield, Peter Garnavich, Mark R. Kennedy +45
The intermediate polar FO Aquarii (FO Aqr) experienced its first-reported low-accretion states in 2016, 2017, and 2018, and using newly available photographic plates, we identify p…
High-Time-Resolution Photometry of AR Scorpii: Confirmation of the White Dwarf's Spin-Down
Robert A. Stiller, Colin Littlefield, Peter Garnavich +3
The unique binary AR Scorpii consists of an asynchronously rotating, magnetized white dwarf (WD) that interacts with its red-dwarf companion to produce a large-amplitude, highly co…
