Abstract : At ARIES Nainital, we have started a photometric monitoring program to study eclipsing binary (EB) and EB candidates to understand their nature and determine their accurate parameters. In recent times, we have carried out photometric analysis of three short period EBs which are low mass contact binary stars. The photometric variability of these EBs is ~1 mag and periods are typically short about 6 hours. In the first phase of our program, we selected CRTS J102211.7+310022, CRTS J163720.4+172047 and CRTS J225831.7+055223 from the Catalina Surveys periodic variable stars Catalog for our analysis using 1.3m telescope. Because of their short period, we were able to cover their full orbit on a single night, easily. We give light curves in V, R and I band. We used PHOEBE and WD code for determination of parameters from their light curves. Multi-band Photometric analysis of these 3 objects is done for first time.
