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,…
Puoko-nui: a flexible high-speed photometric system
P. Chote, D. J. Sullivan, R. Brown +3
We describe a portable CCD-based instrumentation system designed to efficiently undertake high time precision fast photometry. The key components of the system are (1) an externall…
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…
Found: The Progenitors of AM CVn and Supernovae .Ia
Mukremin Kilic, J. J. Hermes, A. Gianninas +7
We present optical and X-ray observations of two tidally distorted, extremely low-mass white dwarfs (WDs) with massive companions. There is no evidence of neutron stars in our Chan…
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).…
