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…
Exciting new features in the frequency spectrum of the EC14026 star HS0702+6043 - Simultaneous g-modes and p-modes in a sdB pulsator
S. Schuh, J. Huber, S. Dreizler +7
The discovery of a long-period g-mode oscillation in the previously known short-period p-mode sdB pulsator HS0702+6043 makes this star an extraordinary object, unique as a member o…
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…
Resolving subdwarf B stars in binaries by HST imaging
U. Heber, S. Moehler, R. Napiwotzki +2
The origin of subluminous B stars is still an unsolved problem in stellar evolution. Single star as well as close binary evolution scenarios have been invoked but until now have me…
