摘要：

We present the first photometric analysis of ASAS J034931-0431.2 and KIC 11413213, two short-period eclipsing contact binaries. Photometric analysis using the Wilson-Devinney method was performed using TESS, Kepler 2, and Gaia DR3 data available. Based on the collected times of minima, period variation studies were carried out and the orbital period was found to show a secular period decrease in both the variables. This can be inferred due to mass transfer or Angular momentum loss in the systems and the same are discussed. From the results obtained, ASAS J034931-0431.2 is an A-type marginal contact binary system with a low mass-ratio of q -0.2, while KIC 11413213 is W-type marginal contact with a high mass-ratio of q -1.2. The evolutionary status of the variables in the study is discussed using the Mass-Radius diagram, the long-time period decrease, the marginal-contact configuration, and the astro-physical parameters of these systems.& COPY; 2023 COSPAR.
