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…
Discovery of two new accreting pulsating white dwarf stars
Anjum S. Mukadam, B. T. Gänsicke, P. Szkody +4
We report the discovery of two new accreting pulsating white dwarf stars amongst the cataclysmic variables of the Sloan Digital Sky Survey: SDSSJ074531.91+453829.5 and SDSSJ091945.…
XMM-Newton Observations of the Cataclysmic Variable GW Lib
Eric J. Hilton, Paula Szkody, Anjum Mukadam +4
XMM-Newton observations of the accreting, pulsating white dwarf in the quiescent dwarf nova GW Librae were conducted to determine if the non-radial pulsations present in previous U…
Abell 43: Longest period Planetary Nebula Nucleus variable
J. -E. Solheim, G. Vauclair, A. S. Mukadam +2
Based on 24h high speed photometry of the hybrid PG 1159 star Abell 43, we have detected 6 sighificant pulsations with periods between 2380 s and 6075 s. A short (4h) run on the al…
