Title: Identification of new cataclysmic variables in the 1RXS and USNO-B1.0 catalogues Authors: D. V. Denisenko, K. V. Sokolovsky
As a result of applying the original optical variability search method on publicly available data, we have found eight new cataclysmic variables and two possible Optically Violent Variable quasars among the previously unidentified X-ray sources in the ROSAT catalogue. We describe the search method and present the characteristics of the newly identified variable stars. The obtained results demonstrate the large potential of the concept of Virtual Observatory for identifying new objects of astrophysical interest.
