The Physics of Mass Transfer in Substellar and Low-Mass Binaries
Samuel Whitebook, Jim Fuller, Kevin Burdge +3
Several dozen binary ultracool and brown dwarf systems have been identified to date. These systems represent valuable probes of star and planet formation at the lowest mass scales.…
Stars stably accreting from substellar objects
Aaron Householder, Kaitlyn Shin, Kevin B. Burdge +11
Substellar objects such as brown dwarfs and planets are generally expected to remain detached from their main-sequence host stars unless orbital decay or stellar expansion brings t…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
Close binary progenitors and ejected companions of thermonuclear supernovae
S. Geier, T. Kupfer, U. Heber +8
Hot subdwarf stars (sdO/Bs) are evolved core helium-burning stars with very thin hydrogen envelopes, which can be formed by common envelope ejection. Close sdB binaries with massiv…
Stellar archaeology with Gaia: the Galactic white dwarf population
Boris Gaensicke, Pier-Emmanuel Tremblay, Martin Barstow +23
Gaia will identify several 1e5 white dwarfs, most of which will be in the solar neighborhood at distances of a few hundred parsecs. Ground-based optical follow-up spectroscopy of t…
The Unseen Population of F to K-type Companions to Hot Subdwarf Stars
J. Girven, D. Steeghs, U. Heber +6
We present a method to select hot subdwarf stars with A to M-type companions using photometric selection criteria. We cover a wide range in wavelength by combining GALEX ultraviole…
