EVR-CB-001: An evolving, progenitor, white dwarf compact binary discovered with the Evryscope
Jeffrey K. Ratzloff, Brad N. Barlow, Thomas Kupfer +7
We present EVR-CB-001, the discovery of a compact binary with an extremely low mass () helium core white dwarf progenitor (pre-He WD) and an unseen low mass…
A new class of pulsating hot subdwarfs
Thomas Kupfer, Evan B. Bauer, Kevin B. Burdge +22
Using high-cadence observations from the Zwicky Transient Facility at low Galactic latitudes, we have discovered a new class of pulsating, hot, compact stars. We have found four ca…
Remnants of Subdwarf Helium Donor Stars Ejected from Close Binaries with Thermonuclear Supernovae
Evan B. Bauer, Christopher J. White, Lars Bildsten
Some binary systems composed of a white dwarf (WD) and a hot subdwarf (sdB) helium star will make contact within the helium burning lifetime of the sdB star. The accreted helium on…
Polluted White Dwarfs: Mixing Regions and Diffusion Timescales
Evan B. Bauer, Lars Bildsten
Many isolated white dwarfs (WDs) show spectral evidence of atmospheric metal pollution. Since heavy element sedimentation timescales are short, this most likely indicates ongoing a…
