Discovery of ZZ Cetis in detached white dwarf plus main-sequence binaries
S. Pyrzas, B. T. Gaensicke, J. J. Hermes +12
We present the first results of a dedicated search for pulsating white dwarfs (WDs) in detached white dwarf plus main-sequence binaries. Candidate systems were selected from a cata…
PSR J1738+0333: The First Millisecond Pulsar + Pulsating White Dwarf Binary
Mukremin Kilic, J. J. Hermes, A. Gianninas +1
We report the discovery of the first millisecond pulsar with a pulsating white dwarf companion. Following the recent discoveries of pulsations in extremely low-mass (ELM, <0.3 Msol…
Seven-Period Asteroseismic Fit of the Kepler DBV
Agnes Kim, Roy Ostensen, J. J. Hermes +1
We present a new, better-constrained asteroseismic analysis of the helium-atmosphere (DB) white dwarf discovered in the field of view of the original Kepler mission. Observations o…
Heavy metals in a light white dwarf: Abundances of the metal-rich, extremely low-mass GALEX J1717+6757
J. J. Hermes, B. T. Gaensicke, D. Koester +9
Using the Hubble Space Telescope, we detail the first abundance analysis enabled by far-ultraviolet spectroscopy of a low-mass (~0.19 Msun) white dwarf (WD), GALEX J1717+6757, whic…
Radius constraints from high-speed photometry of 20 low-mass white dwarf binaries
J. J. Hermes, Warren R. Brown, Mukremin Kilic +10
We carry out high-speed photometry on 20 of the shortest-period, detached white dwarf binaries known and discover systems with eclipses, ellipsoidal variations (due to tidal deform…
A New Gravitational Wave Verification Source
Mukremin Kilic, Warren R. Brown, A. Gianninas +3
We report the discovery of a detached 20 min orbital period binary white dwarf. WD0931+444 (SDSS J093506.93+441106.9) was previously classified as a WD + M dwarf system based on it…
