Discovery of a stripped red giant core in a bright eclipsing binary star
P. F. L. Maxted, D. R. Anderson, M. R. Burleigh +12
We report the serendipitous discovery from WASP archive photometry of a binary star in which an apparently normal A-type star (J0247-25A) eclipses a smaller, hotter subdwarf star (…
Low-mass stellar and substellar companions to sdB stars
S. Geier, L. Classen, P. Bruenner +9
It has been suggested that besides stellar companions, substellar objects in close orbits may be able to trigger mass loss in a common envelope phase and form hot subdwarfs. In an…
Discovery of a stripped red giant core in a bright eclipsing binary system
P. F. L. Maxted, D. R. Anderson, M. R. Burleigh +11
We have identified a star in the WASP archive photometry with an unusual lightcurve due to the total eclipse of a small, hot star by an apparently normal A-type star and with an or…
Radial Velocity Survey of Low-Mass Companions to sdB Stars
L. Classen, S. Geier, U. Heber +1
The origin of subdwarf B (sdB) stars is not fully understood yet since it requires high mass loss at the red giant stage. SdBs in close binary systems are formed via common envelop…
Hypervelocity Stars: Young and Heavy or Old and Light?
Uli Heber, Heiko Hirsch, Heinz Edelmann +4
The first three hyper-velocity stars (HVS) unbound to the Galaxy were serendipitously discovered in 2005. The only suggested origin of hyper-velocity stars is the Galactic Centre a…
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…
