VRI photometry and light curve analysis of short period W UMa-Type 1SWASP J222514.69 + 361643.0
Abstract
We present the first light curve analysis and modeling for the short period close binary 1SWASP J222514.69 + 361643.0. The results show that the system is in over contact with factor ƒ = 53%. The primary component is the massive and hotter one. The system is A-subtype W UMa eclipsing binary with spectral types K2 and K3, respectively.
