摘要：

The bright star 75 Peg is a close binary ellipsoidal variable with a short period (0d.5021035) and an extreme mass ratio (M2/M1 = 0.104). B, V, and R photometric data, along with previously published radial-velocity data, are analyzed and suggest that the primary of the 75 Peg system may be, or is very close to, filling its critical Roche lobe.
