Angular momentum transfer between oscillations and rotation in subdwarf B hybrid pulsators
Fernando Pérez Hernández, Raquel Oreiro, Haili Hu
Context. Subdwarf B pulsators exhibit pressure (p) and/or gravity (g) modes. Their frequency spectra range from very simple, with few frequencies, to very rich, with more than fift…
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…
GALEX J201337.6+092801: The lowest gravity subdwarf B pulsator
Roy H Østensen, Peter I Pápics, Raquel Oreiro +8
We present the recent discovery of a new subdwarf B variable (sdBV), with an exceptionally low surface gravity. Our spectroscopy of J20136+0928 places it at Teff = 32100 +/- 500, l…
A search for new hot subdwarf stars by means of Virtual Observatory tools
R. Oreiro, C. Rodríguez-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…
J08069+1527: A newly discovered high amplitude, hybrid subdwarf B pulsator
A. S. Baran, J. T. Gilker, M. D. Reed +5
We present our discovery of a new hybrid pulsating subdwarf B star, J08069+1527. The effective temperature and surface gravity of 28,500400\,K and 5.370.04\,dex, respecti…
An asteroseismic study of the O9V star HD 46202 from CoRoT space-based photometry
M. Briquet, C. Aerts, A. Baglin +13
The O9V star HD 46202, which is a member of the young open cluster NGC 2244, was observed by the CoRoT satellite in October/November 2008 during a short run of 34 days. From the ve…
