文摘

Six Galactic open clusters (five of them younger than 40 Myr) were investigated for variable stars of all kinds. About 26 000 individual CCD frames of more than 312 h of photometry were analyzed. A detailed time-series analysis was performed resulting in 11 new variables. Several different types of variable stars, such as eclipsing binaries, pulsating, and rotational induced variables were detected. A detailed membership probability study helped to estimate the ages of these variables.
