A SPECTROSCOPIC STUDY OF AG VIRGINIS

Radial velocities determined at the Kitt Peak National Observatory have been analyzed to yield revised orbital elements for the eclipsing binary AG Virginis. These orbital elements are: P = 0.6426514 days, T = JD0 2440660.70, w = 62 , e = 0.14, V0 = -5.6 km sec-1, and K = 70.9 km sec-1. The possible evolutionary state of the system is also discussed. Key words: eclipsing binary - radial velocities - orbit solution
