Light curves of variable stars in {omega} Cen

Using the Australian National University 40 inch (1m) telescope at Siding Spring Observatory, the cluster was observed with a 52'x52' (0.75deg^2^) field for 25 nights, from 2003 May 2 to May 27. A total of 187 variable stars were identified in the field, 81 of which are new discoveries.

This work comprises the widest field variability survey yet undertaken for this cluster. Here we present the V+R light curves and preliminary analysis of the detected variable stars, comprising 58 eclipsing binaries, 69 RR Lyrae stars, 36 long-period variables (P>=2days), and 24 miscellaneous pulsators including 15 SX Phoenicis stars and two type II Cepheids.
