Abstract

We present new precise observations of two short period binary systems observed with 1.0-m telescope in Yunnan Observatory: RV CVn and V1799 Ori. Both of them are short-period early K-type spectral systems. With WD code, complete light curves obtained in RI bands for RV CVn and in BVRI bands for V1799 Ori were analyzed. The Preliminary photometric solutions were derived by us, which reveal that both of them are W-type shallow contact system with degree of overcontact of 9.8% (for RV CVn) and 3.5% (for V1799 Ori). Period change diagram of them is also shown here.
