GD358: three decades of observations for the in-depth asteroseismology of a DBV star
Agnes Bischoff-Kim, J. L. Provencal, P. A. Bradley +38
We report on the analysis of 34 years of photometric observations of the pulsating helium atmosphere white dwarf GD358. The complete data set includes archival data from 1982-2006,…
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…
SDSS J074511.56+194926.5: Discovery of a Metal-Rich and Tidally Distorted Extremely Low Mass White Dwarf
A. Gianninas, J. J. Hermes, Warren R. Brown +5
We present the discovery of an unusual, tidally-distorted extremely low mass white dwarf (WD) with nearly solar metallicity. Radial velocity measurements confirm that this is a com…
A new class of pulsating white dwarf of extremely low mass: the fourth and fifth members
J. J. Hermes, M. H. Montgomery, A. Gianninas +7
We report the discovery of two new pulsating extremely low-mass (ELM) white dwarfs (WDs), SDSS J161431.28+191219.4 (hereafter J1614) and SDSS J222859.93+362359.6 (hereafter J2228).…
Discovery of an ultramassive pulsating white dwarf
J. J. Hermes, S. O. Kepler, Barbara G. Castanheira +5
We announce the discovery of the most massive pulsating hydrogen-atmosphere (DA) white dwarf (WD) ever discovered, GD 518. Model atmosphere fits to the optical spectrum of this sta…
Discovery of pulsations, including possible pressure modes, in two new extremely low mass, He-core white dwarfs
J. J. Hermes, M. H. Montgomery, D. E. Winget +6
We report the discovery of the second and third pulsating extremely low mass white dwarfs (WDs), SDSS J111215.82+111745.0 (hereafter J1112) and SDSS J151826.68+065813.2 (hereafter…
