A deep test of radial differential rotation in a helium-atmosphere white dwarf: I. Discovery of pulsations in PG 0112+104
J. J. Hermes, Steven D. Kawaler, A. Bischoff-Kim +3
We present the detection of non-radial oscillations in a hot, helium-atmosphere white dwarf using 78.7 d of nearly uninterrupted photometry from the Kepler space telescope. With an…
Seismology of an Ensemble of ZZ Ceti Stars
J. C. Clemens, P. C. O'Brien, Bart H. Dunlap +1
We combine all the reliably-measured eigenperiods for hot, short-period ZZ Ceti stars onto one diagram and show that it has the features expected from evolutionary and pulsation th…
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…
A subtle IR excess associated with a young White Dwarf in the Edinburgh-Cape Blue Object Survey
E. Dennihy, John H. Debes, B. H. Dunlap +3
We report the discovery of a subtle infrared excess associated with the young white dwarf EC\,05365--4749 at 3.35 and 4.6\,m. Follow-up spectroscopic observations are consistent…
The Magnetic Cataclysmic Variable LSQ1725-64
J. T. Fuchs, Bart H. Dunlap, E. Dennihy +7
We present new photometry and spectroscopy of the 94m eclipsing binary LSQ1725-64 that provide insight into the fundamental parameters and evolutionary state of this system. We con…
