Discovery of a bright eclipsing cataclysmic variable
D. K. Sing, E. M. Green, S. B. Howell +4
We report on the discovery of J0644+3344, a bright deeply eclipsing cataclysmic variable (CV) binary. Spectral signatures of both binary components and an accretion disk can be see…
HS0702+6043: A star showing both short-period p-mode and long-period g-mode oscillations
S. Schuh, J. Huber, S. Dreizler +4
[Context.] The hot subdwarf B star HS0702+6043 is known as a large-amplitude, short-period p-mode pulsator of the EC14026 type. Its atmospheric parameters place it at the common bo…
Structural Parameters of the Hot Pulsating B Subdwarf PG 1219+534 from Asteroseismology
S. Charpinet, G. Fontaine, P. Brassard +2
We have carried out a detailed asteroseismic analysis of PG 1219+534. Our analysis leads to the identification of the (k,l) indices of nine periods observed in the star PG 1219+534…
On the Purity of the ZZ Ceti Instability Strip: Discovery of More Pulsating DA White Dwarfs on the Basis of Optical Spectroscopy
P. Bergeron, G. Fontaine, M. Billeres +2
We report the discovery of two new ZZ Ceti pulsators, LP 133-144 and HE 1258+0123, selected on the basis of model atmosphere fits to optical spectroscopic data. The atmospheric par…
