A search for new hot subdwarf stars by means of Virtual Observatory tools
R. Oreiro, C. RodrÃguez-López, E. Solano +3
Hot subdwarf stars are faint, blue objects, and are the main contributors to the far-UV excess observed in elliptical galaxies. They offer an excellent laboratory to study close an…
Detection of frequency spacings in the young O-type binary HD 46149 from CoRoT photometry
P. Degroote, M. Briquet, M. Auvergne +15
Using the CoRoT space based photometry of the O-type binary HD46149, stellar atmospheric effects related to rotation can be separated from pulsations, because they leave distinct s…
CoRoT observations of O stars: diverse origins of variability
R. Blomme, M. Briquet, P. Degroote +26
Six O-type stars were observed continuously by the CoRoT satellite during a 34.3-day run. The unprecedented quality of the data allows us to detect even low-amplitude stellar pulsa…
Study of sdO models. Pulsation Analysis
C. RodrÃguez-López, A. Moya, R. Garrido +3
We have explored the possibility of driving pulsation modes in models of sdO stars in which the effects of element diffusion, gravitational settling and radiative levitation have b…
The pulsating hot subdwarf Balloon 090100001: results of the 2005 multisite campaign
A. Baran, R. Oreiro, A. Pigulski +28
We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and sh…
The CARMENES search for exoplanets around M dwarfs. First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems
T. Trifonov, M. Kürster, M. Zechmeister +166
Context: The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M-dwarfs included in the CARMENES sample had been observed before wit…
