摘要
We present a study of selected potential gamma Doradus stars observed in the Geneva photometric system. Eleven stars were monitored at least during the last year of functioning of the 70 cm Swiss telescope at La Silla, leading to about one thousand photometric measurements and permitting a detailed analysis of these stars. After the analysis, five stars are thought to be constant stars. We report three new gamma Dor stars. A spectroscopic campaign has been started at La Silla with the new 1m20 Swiss telescope, equipped with the spectrograph CORALIE, of which we show the results for the selected stars.
