Deep census of variable stars in a VLT/VIMOS field in Carina

Aims. We searched for variable stars in deep V-band images of a field towards the Galactic plane in Carina. Methods. The images were taken with the VIMOS instrument at ESO VLT during 4 contiguous nights in April 2005. We detected 348 variables among 50 897 stars in the magnitude range between V = 15...
