Abstract:
We have gathered and analysed a timeseries of 1493 high-quality
multicolour Geneva photometric data of the B3V β Cep star
Hd 129929. The dataset has a time base of 21.2 years. The occurrence
of a beating phenomenon is evident from the data. We find evidence for
the presence of at least six frequencies, among which we see
components of two frequency multiplets with an average spacing of
∼0.0121c/d which points towards very slow rotation. This result is in
agreement with new spectroscopic data of the star and also with
previously taken UV spectra. We provide the amplitudes of the six
frequencies in all seven photometric filters. The metal content of the
star is Z=0.018±0.004. All these observational results will be used
to perform detailed seismic modelling of this massive star in a
subsequent paper.
