White Dwarf Variability with gPhoton: Pulsators
Michael A. Tucker, Scott W. Fleming, Ingrid Pelisoli +10
We present results from a search for short time-scale white dwarf variability using \texttt{gPhoton}, a time-tagged database of \textit{GALEX} photon events and associated software…
Probing the structure of Kepler ZZ Ceti stars with full evolutionary models-based asteroseismology
Alejandra D. Romero, A. H. Córsico, B. Castanheira +8
We present an asteroseismological analysis of four ZZ Ceti stars observed with \emph{Kepler}: GD 1212, SDSS J113655.17+040952.6, KIC 11911480 and KIC 4552982, based on a grid of fu…
Pulsating White Dwarfs
S. O. Kepler, Alejandra D. Romero
The Sloan Digital Sky Survey has allowed us to increase the number of known white dwarfs by a factor of five and consequently the number of known pulsating white dwarfs also by a f…
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…
Four New Massive Pulsating White Dwarfs Including an Ultramassive DAV
Brandon Curd, A. Gianninas, Keaton J. Bell +5
We report the discovery of four massive () ZZ Ceti white dwarfs, including an ultramassive star. We obtained ground based, time-series photometry…
White Dwarf Stars
S. O. Kepler, Alejandra Daniela Romero, Ingrid Pelisoli +1
White dwarf stars are the final stage of most stars, born single or in multiple systems. We discuss the identification, magnetic fields, and mass distribution for white dwarfs dete…
