Variations of Ap stars in the Geneva system
Listed in IVOA Registry (Virtual Observatory)
The photometric behaviour of 21 Ap stars has been analyzed from observations obtained in the Geneva system.
Description
Variability has been detected for 9 Ap stars, as well as for a star which initially was a comparison star. Preliminary values for the periods are presented as well as an analytical description of the light curves.
The material has been collected during a 23-night observing run at La Silla with the 70cm telescope of the Geneva Observatory equipped with the standard Geneva photometer. The parameters of a second-order cosine fit to the lightcurves are stored in the accompanying table. Time origin is JD 2450000.0.

The 17 phase diagrams for each of the 9 stars are presented in 9 postscript files. The observational data are superimposed on the Fourier fit. Data are differential, except for HD 191439 and HD 192674 which had no suitable comparisons.
