Subdwarf B binaries in the Edinburgh-Cape Survey
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2
We give an update of the results of a campaign to obtain orbital solutions of subdwarf B stars from the Edinburgh-Cape survey (Stobie et al. 1997). To date we have obtained blue sp…
SDSS J124058.03-015919.2: A new AM CVn star with a 37-minute orbital period
G. H. A. Roelofs, P. J. Groot, T. R. Marsh +3
We present high time resolution VLT spectroscopy of SDSS J124058.03-015919.2, a new helium-transferring binary star identified in the Sloan Digital Sky Survey. We measure an orbita…
Subdwarf B Binaries from the Edinburgh--Cape Survey
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2
We present the first results of a campaign to obtain orbital solutions of subdwarf B (sdB) stars from the Edinburgh-Cape survey. We have obtained blue spectra of 35 sdBs, 20 of whi…
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…

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…
