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…
Massive unseen companions to hot faint underluminous stars from SDSS (MUCHFUSS) - Analysis of seven close subdwarf B binaries
S. Geier, P. F. L. Maxted, R. Napiwotzki +12
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dw…
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…
Ground-based observations of Kepler asteroseismic targets
K. Uytterhoeven, R. Szabo, J. Southworth +42
We present the ground-based activities within the different working groups of the Kepler Asteroseismic Science Consortium (KASC). The activities aim at the systematic characterizat…
A survey for pulsating subdwarf B stars with the Nordic Optical Telescope
R. H. Ostensen, R. Oreiro, J. -E. Solheim +7
A search programme for pulsating subdwarf B stars was conducted with the Nordic Optical Telescope on La Palma over 59 nights between 1999 and 2009. The purpose of the programme was…
Study of sdO models: mode trapping
C. Rodríguez-López, A. Moya, R. Garrido +3
We present the first description of mode trapping for sdO models. Mode trapping of gravity modes caused by the He/H chemical transition is found for a particular model, providing a…
