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…
First Kepler results on compact pulsators VII. Pulsating subdwarf B stars detected in the second half of the survey phase
A. S. Baran, S. D. Kawaler, M. D. Reed +10
We present five new pulsating subdwarf B (sdB) stars discovered by the Kepler spacecraft during the asteroseismology survey phase. We perform time-series analysis on the nearly con…
RAT J0455+1305: A rare hybrid pulsating subdwarf B star
A. S. Baran, J. T. Gilker, L. Fox-Machado +2
We present results on the second-faintest pulsating subdwarf B (sdB) star known, RAT J0455+1305, derived from photometric data obtained in 2009. It shows both short and long period…
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…
First Kepler results on compact pulsators VIII: Mode identifications via period spacings in mode pulsating Subdwarf B stars
M. D. Reed, A. Baran, A. C. Quint +13
We investigate the possibility of nearly-equally spaced periods in 13 hot subdwarf B (sdB) stars observed with the Kepler spacecraft and one observed with CoRoT. Asymptotic limits…
First Kepler results on compact pulsators VI. Targets in the final half of the survey phase
R. H. Østensen, R. Silvotti, S. Charpinet +29
We present results from the final six months of a survey to search for pulsations in white dwarfs and hot subdwarf stars with the Kepler spacecraft. Spectroscopic observations are…
