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).…
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…
