The ^12C(alpha,gamma)^16O Nuclear Reaction Rate from Asteroseismology of the DBV White Dwarf CBS 114
T. S. Metcalfe, G. Handler
We have identified seven independent pulsation modes in the helium-atmosphere variable (DBV) white dwarf star CBS 114, based on 65 hours of time-resolved CCD photometry from the 0.…

The photometric behaviour of the peculiar PG1159 star HS2324+3944 at high frequency resolution
R. Silvotti, S. Dreizler, G. Handler +1
We present the results from 135 hours of nearly continuous time series photometry on the ``hybrid'' (H-rich) PG1159 variable star HS2324+3944, obtained in August-September 1997. Th…

Towards a seismic model of the Delta Scuti star XX Pyxidis
A. A. Pamyatnykh, W. A. Dziembowski, G. Handler +1
Frequencies of 13 oscillation modes in the star XX Pyxidis (CD-24 7599) are accurately measured but for none of the modes the spherical harmonic degree l is known. We present resul…
