The EXOTIME project: Signals in the diagrams of the rapidly pulsating subdwarfs DW Lyn, V1636 Ori, QQ Vir, and V541 Hya
F. Mackebrandt, S. Schuh, R. Silvotti +17
We aim to investigate variations in the arrival time of coherent stellar pulsations due to the light-travel time effect to test for the presence of sub-stellar companions. Those co…
Three ways to solve the orbit of KIC11558725: a 10 day beaming sdB+WD binary with a pulsating subdwarf
J. H. Telting, R. H. Østensen, A. S. Baran +16
The recently discovered subdwarf B (sdB) pulsator KIC11558725 features a rich g-mode frequency spectrum, with a few low-amplitude p-modes at short periods, and is a promising targe…
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…
Kepler observations of the beaming binary KPD 1946+4340
S. Bloemen, T. R. Marsh, R. H. Østensen +24
The Kepler Mission has acquired 33.5d of continuous one-minute photometry of KPD 1946+4340, a short-period binary system that consists of an sdB and a white dwarf. In the light cur…
First Kepler results on compact pulsators V: Slowly pulsating subdwarf B stars in short-period binaries
S. D. Kawaler, M. D. Reed, R. H. Østensen +15
The survey phase of the Kepler Mission includes a number of hot subdwarf B (sdB) stars to search for nonradial pulsations. We present our analysis of two sdB stars that are found t…
First Kepler results on compact pulsators I. Survey target selection and the first pulsators
R. H. Østensen, R. Silvotti, S. Charpinet +25
We present results from the first two quarters of a survey to search for pulsations in compact stellar objects with the Kepler spacecraft. The survey sample and the various methods…
2M1938+4603: A rich, multimode pulsating sdB star with an eclipsing dM companion observed with Kepler
R. H. Østensen, E. M. Green, S. Bloemen +16
2M1938+4603 (KIC 9472174) displays a spectacular light curve dominated by a strong reflection effect and rather shallow, grazing eclipses. The orbital period is 0.126 days, the sec…
