Towards Asteroseismology of PG1605+072
A. Tillich, U. Heber, S. J. O'Toole +2
We present our attempt to characterise the frequency spectrum of the bright V 361 Hya star PG1605072 from atmospheric parameter and radial velocity variations through a spectros…

New Light Curves and Spectra of the close PG1159 Binary System SDSSJ212531.92-010745.9
Sonja Schuh, Thorsten Nagel, Iris Traulsen +1
Methods to measure masses of PG1159 stars in order to test evolutionary scenarios are currently based on spectroscopic masses or asteroseismological mass determinations. SDSSJ21253…

Light curve analysis of the hybrid sdB pulsators HS0702+6043 and HS2201+2610
R. Lutz, S. Schuh, R. Silvotti +6
We present the detection of low-amplitude, long-period g-modes in two individual sdBV stars which are known to be p-mode pulsators. Only few of these hybrid objects, showing both p…
