Abstract

The photometric and spectroscopic data for three double-lined detached eclipsing binaries were collected from the photometric and spectral surveys. The light and radial velocity curves of each binary system were simultaneously analyzed by using Wilson-Devinney (WD) code, and the absolute physical and orbital parameters of these binaries were derived. The masses of both components of ASASSN-V J063123.82+192341.9 were found to be M1=1.088±0.016M_1 = 1.088 \pm 0.016 and M2=0.883±0.016 MM_2 = 0.883 \pm 0.016\ M_{\odot}; and those of ASAS J011416+0426.4 were determined to be M1=0.934±0.046M_1 = 0.934 \pm 0.046 and M2=0.754±0.043MM_2 = 0.754 \pm 0.043 M_{\odot}; those of MW Aur were derived to be M1=2.052±0.196M_1 = 2.052 \pm 0.196 and M2=1.939±0.193 MM_2 = 1.939 \pm 0.193\ M_{\odot}. At last, the evolutionary status of these detached binaries was discussed based on their absolute parameters and the theoretical stellar models.
