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…
Discovery of magnetic fields in hot subdwarfs
S. J. O'Toole, S. Jordan, S. Friedrich +1
We present initial results of a project to measure mean longitudinal magnetic fields in a group of sdB/OB/O stars. The project was inspired by the discovery of three super-metal-ri…
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…
