Orbital periods and component masses of three double white dwarfs
A. Rebassa-Mansergas, S. G. Parsons, E. Garcia-Berro +4
The merger of close double white dwarfs (CDWDs) is one of the favourite evolutionary channels for producing Type Ia supernovae (SN Ia). Unfortunately, current theories of the evolu…
What's the nature of sdA stars?
Ingrid Pelisoli, S. O. Kepler, D. Koester +1
White dwarfs with log g lower than 7.0 are called Extremely Low Mass white dwarfs (ELMs). They were first found as companions to pulsars, then to other white dwarfs and main sequen…
Understanding Systematics in ZZ Ceti Model Fitting to Enable Differential Seismology
J. T. Fuchs, Bart H. Dunlap, J. C. Clemens +3
We are conducting a large spectroscopic survey of over 130 Southern ZZ Cetis with the Goodman Spectrograph on the SOAR Telescope. Because it employs a single instrument with high U…
Solar Abundances of Rock Forming Elements, Extreme Oxygen and Hydrogen in a Young Polluted White Dwarf
J. Farihi, D. Koester, B. Zuckerman +5
The Teff = 20,800 K white dwarf WD 1536+520 is shown to have broadly solar abundances of the major rock forming elements O, Mg, Al, Si, Ca, and Fe, together with a strong relative…
The search for ZZ Ceti stars in the original Kepler mission
S. Greiss, J. J. Hermes, B. T. Gaensicke +11
We report the discovery of 42 white dwarfs in the original Kepler mission field, including nine new confirmed pulsating hydrogen-atmosphere white dwarfs (ZZ Ceti stars). Guided by…
