Multi-wavelength photometric variation of PG1605+072
S. Schuh, S. Dreizler, U. Heber +8
In a large coordinated attempt to further our understanding of the -mode pulsating sdB star PG1605+072, the Multi-Site Spectroscopic Telescope (MSST) collaboration has obtained…
HVS7: a chemically peculiar hyper-velocity star
N. Przybilla, M. F. Nieva, A. Tillich +3
Context: Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelera…
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…
Searching for Hyper-Velocity Stars
A. Tillich, U. Heber, H. Hirsch
We present our survey for subluminous hyper-velocity candidates, which has been successfully initiated at the ESO NTT and the Calar Alto 3.5 m telescope.
The MSST Campaign: II.Effective temperature and gravity variations in the multi-periodic pulsating subdwarf B star PG1605+072
A. Tillich, U. Heber, S. J. O'Toole +2
Stellar oscillations are an important tool to probe the interior of a star. Subdwarf B stars are core helium burning objects, but their formation is poorly understood as neither si…
Time resolved spectroscopy of the multiperiodic pulsating subdwarf B star PG1605+072
A. Tillich, U. Heber, S. J. O'Toole
We present results for the 2m spectroscopic part of the MultiSite Spectroscopic Telescope campaign, which took place in May/June 2002. In order to perform an asteroseismological an…
