Dwarf Nova Oscillations and Quasi-Periodic Oscillations in Cataclysmic Variables - VIII. VW Hyi in outburst observed with the Southern African Large Telescope
P. A. Woudt, B. Warner, D. O'Donoghue +4
We analyse four light curves obtained at high time resolution (~ 0.1 s) with the 11-m Southern African Large Telescope, at the ends of two normal outbursts and one superoutburst of…
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…
First science with SALT: peering at the accreting polar caps of the eclipsing polar SDSS J015543.40+002807.2
D. O'Donoghue, D. A. H. Buckley, L. A. Balona +48
We describe briefly the properties of the recently completed Southern African Large Telescope (SALT), along with its first light imager SALTICAM. Using this instrument, we present…
Whole Earth Telescope observations of BPM 37093: a seismological test of crystallization theory in white dwarfs
A. Kanaan, A. Nitta, D. E. Winget +3
BPM 37093 is the only hydrogen-atmosphere white dwarf currently known which has sufficient mass (~ 1.1 M_sun) to theoretically crystallize while still inside the ZZ Ceti instabilit…
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…
