The Potential of the Timing Method to Detect Evolved Planetary Systems
Roberto Silvotti, Robert Szabo, Pieter Degroote +2
The timing method, using either stellar pulsations or eclipse timing of close binaries as a clock, is proving to be an efficient way to detect planets around stars that have evolve…
The EXOTIME project: a status report on PG 1325+101 (QQ Vir)
Serena Benatti, Roberto Silvotti, Riccardo U. Claudi +7
After the discovery of V391 Peg b, the first planet detected around a post Red Giant phase star (Silvotti et al. 2007), the EXOTIME (EXOplanet search with the TIming MEthod) projec…
The Hyper-MUCHFUSS project: probing the Galactic halo with sdB stars
A. Tillich, U. Heber, S. Geier +7
High-velocity stars in the Galactic halo, e.g. the so-called hyper-velocity stars (HVS), are important tracers of the properties of the dark matter halo, in particular its mass. Ba…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Observational asteroseismology of hot subdwarf stars
Roy H. Østensen
Hot subdwarf stars are particularly challenging for asteroseismology due to their rapid pulsation periods, intrinsic faintness and relative rarity both in the field and in clusters…
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…
