Discovery of a Long-Period Photometric Variation in the V361 Hya Star HS 0702+6043
S. Schuh, J. Huber, E. M. Green +4
We report the discovery of a long-period g-mode oscillation in the previously known short-period p-mode sdB pulsator HS 0702+6043. This makes this star an extraordinary object, uni…
Subluminous O stars from the ESO Supernova Progenitor Survey - Observation versus Theory
A. Stroeer, U. Heber, T. Lisker +2
The ESO Supernova Progenitor Survey (SPY) has identified 58 (mostly helium-rich) subluminous O stars. We use the Balmer line strength to distinguish sdO from He-sdO (no Balmer line…
Double degenerates and progenitors of supernovae type Ia
R. Napiwotzki, L. Yungelson, G. Nelemans +12
We report on systematic radial velocity surveys for white dwarf - white dwarf binaries (double degenerates - DDs) including SPY (ESO Supernovae Ia progenitor survey) recently carri…
Stellar wind signatures in sdB stars?
U. Heber, P. F. L. Maxted, T. R. Marsh +2
Subdwarf B (sdB) stars form the blue end of the horizonal branch. Their peculiar atmospheric abundance patterns are due to diffusion processes. However, diffusion models fail to ex…
Towards asteroseismology of the non-radial pulsating sdB star PG 1605+072
S. Falter, U. Heber, S. Dreizler +2
The recently discovered new class of sdB pulsators (sdBV) offers a powerful possibility for the investigation of their interior and thus their evolutionary history. The first step…
