Variable Stars in the field of {omega} Cen
Listed in IVOA Registry (Virtual Observatory)
We present results of a photometric survey for variable stars in the field of the globular cluster Omega Centauri.
Description
The observed region was centered roughly on the cluster core and covered 644arcmin^2^. The cluster was monitored on 59 nights in 1999 and 2000.
A total of 117 new variables were identified. Among them there are 16 RR Lyr-type stars, 35 SX Phe variables and 26 eclipsing binaries. A comprehensive catalog including all variable stars so far reported from the cluster field is presented.

We list basic photometric properties and provide finding charts for a total of 392 objects. For 313 of them new BV light curves were obtained. The presented sample includes several interesting variables, such as SX Phe stars with extremely short periods of pulsation and several candidates for pulsating K giants.
Optical counterparts to 9 X-ray sources detected by XMM and Chandra telescopes were identified: all of them are likely to be foreground variables not related to the cluster.
