One Million Variable Stars from the OGLE Survey

Igor Soszyński

During its long history, the OGLE survey detected, classified and published more variable stars than all other astronomical projects put together. Currently the OGLE Collection of Variable Stars contains nearly one million objects: Cepheids, RR Lyr stars, long-period variables, eclipsing binaries and other variable sources in our Galaxy and in the Magellanic Clouds. These samples have been used in countless analyzes focusing on the stellar variability itself and on the structure of galaxies to which they belong. We present the most spectacular results obtained based on the OGLE Collection of Variable Stars during the last 25 years, with particular emphasis on the most recent achievements.
