Description
Radial velocity measurements of a group of Ap stars were obtained in May
and December 1987 using a Fabry-Perot interferometric stellar
oscillation spectrometer that has been improved to enable the instrument
to be referenced to the Cd blue line. Observations of the rapidly
oscillating Ap stars 33 Lib and HR 1217 were analyzed in order to search
for radial velocity variations corresponding to the photometric periods
found in these stars. The radial velocity and photometric data sets have
been reduced with the aid of a weighted sine wave fitting routine. For
HR 1217, a peak at 2.72 mHz and an amplitude of about 240 m/s are found.
