High-resolution spectropolarimetric observations of hot subdwarfs
P. Petit, V. Van Grootel, S. Bagnulo +3
We report on high-resolution spectropolarimetric observations of the hot subdwarf stars HD 76431 and Feige 66, using the ESPaDOnS echelle spectropolarimeter at CFHT. We compute cro…
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…
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…
