[60.07] The Eclipsing Spectroscopic Binary System V505 Persei

L. A. Marschall (Gettysburg Coll.), R. P. Stefanik (CfA), C. H. Lacy (Univ. of Arkansas), D. B. Williams (Indianapolis, IN), F. Agerer (Zweikirchen, Germany)

We have obtained extensive spectroscopic and photometric observations of the bright double-lined eclipsing binary V505 Persei (SAO 23229) discovered in 1989 by Kaiser. The system consists of two nearly identical F5 main sequence stars in a 4.2 day orbit. The observations enable us to derive high precision (<1stellar masses, along with other properties of the binary system. These values agree well with current stellar structure models, and add to the growing base of fundamental stellar data applicable to tests of stellar evolution theory.
