Towards ensemble asteroseismology of the young open clusters Chi Persei and NGC 6910
S. Saesen, A. Pigulski, F. Carrier +71
As a result of the variability survey in Chi Persei and NGC6910, the number of Beta Cep stars that are members of these two open clusters is increased to twenty stars, nine in NGC6…
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…
A multisite photometric campaign on the Pre-Main-Sequence delta Scuti pulsator IP Per
V. Ripepi, S. Bernabei, M. Marconi +18
We present the results of a photometric multisite campaign on the Scuti Pre-Main-Sequence star IP Per. Nine telescopes have been involved in the observations, with a total of a…
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…
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…
