Description
Radial velocity measurements were taken of a group of Ap stars using an
improved FP-ISOS. Observations were made using the 1.5m TCS on Tenerife
in May 1987 and December 1987. The already known rapidly oscillating Ap
stars 33 Lib and HR1217 were observed in order to search for radial
velocity variations corresponding to the photometric periods found in
these stars. Simultaneous photometric measurements were made on HR1217
on the last two nights using the nearby 0.5m telescope. The radial
velocity and photometric data sets were reduced using a weighted sine
wave fitting routine. Promising results are obtained for HR1217, while
results obtained for the other Ap stars observed do not allow any
conclusion. Data taken several years ago on Alpha Cir was re-examined
and the results obtained are also discussed.
