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…
The sdB pulsating star V391 Peg and its putative giant planet revisited after 13 years of time-series photometric data
R. Silvotti, S. Schuh, S. -L. Kim +10
V391 Peg (alias HS2201+2610) is a subdwarf B (sdB) pulsating star that shows both p- and g-modes. By studying the arrival times of the p-mode maxima and minima through the O-C meth…
EXOTIME: searching for planets and measuring Pdot in sdB pulsators
Ronny Lutz, Sonja Schuh, Roberto Silvotti
We review the status of the EXOTIME project (EXOplanet search with the TIming MEthod). The two main goals of EXOTIME are to search for sub-stellar companions to sdB stars in wide o…
The EXOTIME targets HS0702+6043 and HS0444+0458
Ronny Lutz, Sonja Schuh, Roberto Silvotti
Pulsations in subdwarf B (sdB) stars are an important tool to constrain the evolutionary status of these evolved objects. Interestingly, the same data used for this asteroseismolog…
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…
EXOTIME: searching for planets around pulsating subdwarf B stars
Sonja Schuh, Roberto Silvotti, Ronny Lutz +27
In 2007, a companion with planetary mass was found around the pulsating subdwarf B star V391 Pegasi with the timing method, indicating that a previously undiscovered population of…
