Description
Cataclysmic Variables (CVs) are close binaries consisting of an accreting white dwarf and a low-mass main sequence companion. We have initiated in searching new CVs using their outburst properties with the primary aim to identify short-period systems which are rare but are great of importance to understand close binary evolution. Here, we present time-resolved photometry of new CVs in superoutburst discovery by Catalina Real-Time Transient Survey (CRTS). The observations have been carried out at 2.4 m Thai National Telescope, Doi Inthanon, and 0.6 m PROMPT8 telescope, located at Cerro Tololo Observatory, Chile. Superhump structure found in their light curves suggested that these CVs are short- period systems with the orbital period below the 2-3 h period gap. Furthermore, we will discuss recent status of CRTS CVs sample compared to the previously known CVs discovered by various means.
