Photometric study of two marginal contact binaries in SMC

This paper presents the photometric solutions of two marginal contact binaries in Small Magellanic cloud (SMC). The data was acquired from Optical Gravitational Lensing Experiment (OGLE) catalogue and the photometric solutions were obtained using Wilson-Devinney (WD) v2003 program. Results reveal that these systems belong to the short period contact binaries of W-subtype. High mass-ratio and low contact factor of both the systems indicates that they have recently evolved into a marginal contact stage. Estimated absolute dimensions and evolutionary stages of these variables are in good agreement with physical properties of Low Mass Contact Binaries (LMCB).
