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…

The frequency of transiting planetary systems around polluted white dwarfs

Akshay Robert, Jay Farihi, Vincent Van Eylen +6

This paper investigates the frequency of transiting planetary systems around metal-polluted white dwarfs using high-cadence photometry from ULTRACAM and ULTRASPEC on the ground, an…

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…
