摘要：

We present the simultaneous light and radial velocity curve analysis of two contact binaries in Pegasus using the Wilson-Devinney code. The following absolute astrophysical parameters are determined: masses, radii and effective temperatures. BB Peg is a W-subtype W UMa-type binary, components of which are main sequence stars with 0.50 M-circle dot and 1.40 M-circle dot. The radii of its components are R-1 = 0.81 R-circle dot and R-2 = 1.28 R-circle dot. V407 Peg is an A-subtype contact binary composed of two subgiant components with masses 1.70 M-circle dot and 0.43 M-circle dot, and radii R-1 = 2.17 R-circle dot and R-2 = 1.25 R-circle dot. Comparisons with the theoretical models for solar composition by Girardi et al. (2000) confirms our classification and supports the results.
