Description:
We present ground-based follow-up photometry in the Geneva
seven-colour photometric system of six new β Cep stars. The
variability of these objects was originally found from the HIPPARCOS
mission. The new data provided here allowed us to confirm their β
Cep-type nature, to detect the pulsational frequencies and to identify
the degrees of the pulsation modes.
For definitions of the Geneva photometric system, see GCPD/13.
