The Dushak–Erekdag Survey of roAp Stars

Abstract. The search of roAp stars at Mt. Dushak–Erekdag Observatory was started in 1992 using the 0.8 m Odessa telescope equipped with a two-star high-speed photometer. We have observed more than a dozen stars so far and discovered HD 99563 as roAp star while BD+8087 is suspected to have rapid oscillations. Negative results of our observations for the search of rapid oscillations in four stars in NGC 752 are also discussed. Key words. Stars: chemically peculiar—stars: oscillations—stars: variables: other—techniques: photometric
