Evidence from K2 for rapid rotation in the descendant of an intermediate-mass star
J. J. Hermes, Steven D. Kawaler, A. D. Romero +9
Using patterns in the oscillation frequencies of a white dwarf observed by K2, we have measured the fastest rotation rate, 1.13(02) hr, of any isolated pulsating white dwarf known…
Modeling the Spectra of Dense Hydrogen Plasmas: Beyond Occupation Probability
T. A. Gomez, M. H. Montgomery, T. Nagayama +2
Accurately measuring the masses of white dwarf stars is crucial in many astrophysical contexts (e.g., asteroseismology and cosmochronology). These masses are most commonly determin…
Reaching Higher Densities for Laboratory White Dwarf Photospheres to Measure Spectroscopic Line Profiles
Ross E. Falcon, J. E. Bailey, T. A. Gomez +5
As part of our laboratory investigation of the theoretical line profiles used in white dwarf atmosphere models, we extend the electron-density () range measured by our e…
The First Six Outbursting Cool DA White Dwarf Pulsators
Keaton J. Bell, J. J. Hermes, M. H. Montgomery +4
Extensive observations from the Kepler spacecraft have recently revealed a new outburst phenomenon operating in cool pulsating DA (hydrogen atmosphere) white dwarfs (DAVs). With th…
Outbursts in two new cool pulsating DA white dwarfs
Keaton J. Bell, J. J. Hermes, M. H. Montgomery +9
The unprecedented extent of coverage provided by Kepler observations recently revealed outbursts in two hydrogen-atmosphere pulsating white dwarfs (DAVs) that cause hours-long incr…
A comparative analysis of the observed white dwarf cooling sequence from globular clusters
Fabíola Campos, P. Bergeron, A. D. Romero +8
We report our study of features at the observed red end of the white dwarf cooling sequences for three Galactic globular clusters: NGC\,6397, 47\,Tucanae and M\,4. We use deep colo…
