DOI: 10.1007/s10509-017-3227-4
Abstract: We carried out high-precision photometric observations of three eclipsing ultrashort-period contact binaries (USPCBs). Theoretical models were fitted to the light curves by means of the Wilson-Devinney code. The solutions suggest that the three targets have… read more here.

DOI: 10.1088/1538-3873/ac1ac1
Abstract: We use the idea of repeat measurement to determine the mean value and error of light curve solution parameters of contact binaries. Our simulation is realized by the Monte Carlo algorithm and Wilson–Devinney code. This… read more here.

DOI: 10.1088/1674-4527/18/5/55
Abstract: Traditionally, some physical details (e.g., magnetic braking, energy transfer, angular momentum loss, etc.) have to be taken into consideration during investigations into the evolution of contact binaries. However, the real evolutionary processes which usually contain… read more here.

DOI: 10.1093/mnras/stad1465
Abstract: The theoretical relations between the orbital period and mean densities of component stars of contact binaries are deduced. It is found that the orbital period of a contact binary is inversely proportional to the square… read more here.

DOI: 10.1093/mnras/stz715
Abstract: The period distribution of contact binaries exhibits a very sharp short period cut-off at 0.22 days. In order to provide valuable information on this short period limit, we observed ten totally eclipsing contact binaries with… read more here.
