Whole Earth Telescope observations of the hot helium atmosphere pulsating white dwarf EC 20058-5234

WET Collaboration, D. J. Sullivan, T. S. Metcalfe +22

We present the analysis of a total of 177h of high-quality optical time-series photometry of the helium atmosphere pulsating white dwarf (DBV) EC 20058-5234. The bulk of the observ…

The pulsation modes of the pre-white dwarf PG 1159-035

J. E. S. Costa, S. O. Kepler, D. E. Winget +74

PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…

Observations of the pulsating subdwarf B star Feige 48: Constraints on evolution and companions

M. D. Reed, S. D. Kawaler

Since pulsating subdwarf B (sdBV or EC14026) stars were first discovered (Kilkenny et al, 1997), observational efforts have tried to realize their potential for constraining the in…

Discover of the "missing" mode in HR 1217 by the Whole Earth Telescope

D. W. Kurtz, S. D. Kawaler, R. L. Riddle et al.

HR 1217 is a prototypical rapidly oscillating Ap star that has presented a test to the theory of nonradial stellar pulsation. Prior observations showed a clear pattern of five mode…

Understanding the Cool DA White Dwarf, G29-38

S. J. Kleinman, R. E. Nather, D. E. Winget +37

The white dwarfs are promising laboratories for the study of cosmochronology and stellar evolution. Through observations of the pulsating white dwarfs, we can measure their interna…
