Eclipsing binaries in the galactic globular cluster Omega Centauri

摘要

We present a photometric survey aimed at the identification of variable stars in the galactic globular cluster Cen. Our photometric catalogue is based on ~ 400 exposures of the central region of the cluster(Fov ~ 15 × 15) collected with the Danish Telescope. The catalogue has an accuracy of about ~ 0.02 mag at B ~ 18 mag. We present here preliminary results concerning the possible identification of two variable stars and an eclipsing binary candidate in Cen.
