9+ frequencies for V534 Tauri, a delta Scuti variable in the Pleiades. Results of the STEPHI IX campaign
Résumé
New observations of V534 Tau were performed during the STEPHI IX campaign in November 1998. An overall run of 285 h of data has been collected from three sites over a period of 23 days. Period analysis reveals a rich oscillation spectrum with nine frequencies above the 99% confidence level. This oscillation spectrum spans a large range of frequencies, from 179 to 525 muHz (15.52 to 45.36 cycles per day). A preliminary comparison with models suggests that the observed modes would lie in the range of modes from g1 or g2 to p4 or p5, depending on the rotation rate considered for V534 Tau.
