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…

Subdwarf B (sdB) stars form the blue end of the horizonal branch (EHB). Their peculiar atmospheric abundance patterns are due to diffusion processes. However, diffusion models fail…
Subluminous B Stars and Progenitors of Helium Core White Dwarfs
U. Heber
Subluminous B (sdB) stars can result from stable Roche lobe overflow or common envelope ejection in close binary systems. The companions are either low mass main sequence stars or…
Photometric and Spectroscopic Monitoring of the sdBV star PG 1605+072: The Multi-Site Spectroscopic Telescope (MSST) Project
U. Heber, S. Dreizler, S. L. Schuh +2
A small fraction of subluminous B stars show short-period, multiperiodic light variations and form the new class of pulsating star known as EC 14026 variables, after the prototype.…
The Rotational Velocity of Helium-rich Pre-White Dwarfs
T. Rauch, S. Koeper, S. Dreizler +3
Previous investigations on hydrogen-rich white dwarfs generally yield only very small rotational velocities (v_rot sin i). We have analyzed line profiles in high-resolution optical…
