Variations of AP stars in the Geneva system
The photometric behaviour of 21 Ap stars has been analyzed fromobservations obtained in the Geneva system. Variability has beendetected for 9 Ap stars, as well as for a star which initially was acomparison star. Preliminary values for the periods are presented aswell as an analytical description of the light curves. based onobservations made at the Swiss telescope of the European SouthernObservatory, La Silla, Chile. Complete Table 4 is available inelectronic form at the CDS via anonymous ftp 130.79.128.5 orhttp://cdsweb.u-strasbg.fr/Abstract.html and full figures are accessibleon the on-line version of the paper.
