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…
NGTS-33b: A Young Super-Jupiter Hosted by a Fast Rotating Massive Hot Star
Douglas R. Alves, James S. Jenkins, Jose I. Vines +22
In the last few decades planet search surveys have been focusing on solar type stars, and only recently the high-mass regimes. This is mostly due to challenges arising from the lac…
The First Spin-Orbit Obliquity of an M dwarf/brown dwarf System: An eccentric and aligned TOI-2119 b
Lauren Doyle, Caleb I. Cañas, Jessica E. Libby-Roberts +15
We report the first instance of an M dwarf/brown dwarf obliquity measurement for the TOI-2119 system using the Rossiter-McLaughlin effect. TOI-2119 b is a transiting brown dwarf or…
The evolutionary history of GD1400, a white dwarf-brown dwarf binary
S. L. Casewell, M. R. Burleigh, R. Napiwotzki +6
GD1400AB was one of the first known white dwarfbrown dwarf binaries, and is the only one of these systems where the white dwarf is a ZZ Ceti pulsator. Here we present both radia…
The only inflated brown dwarf in an eclipsing white dwarf-brown dwarf binary: WD1032+011B
Jenni R. French, Sarah L. Casewell, Rachael C. Amaro +9
Due to their short orbital periods and relatively high flux ratios, irradiated brown dwarfs in binaries with white dwarfs offer better opportunities to study irradiated atmospheres…
Primeval very low-mass stars and brown dwarfs -- VIII. The first age benchmark L subdwarf, a wide companion to a halo white dwarf
Z. H. Zhang, R. Raddi, A. J. Burgasser +12
We report the discovery of five white dwarf + ultracool dwarf systems identified as common proper motion wide binaries in the Gaia Catalogue of Nearby Stars. The discoveries includ…
