Subjecteclipsing detached; Wilson-Devinney radial velocities
Abstract
Radial velocity data and photometric light curves (in the B. V, and Ic passbands) for the detached eclipsing binary AG Leo Minoris were acquired–apparently for the first time–and are reported here. Roche modelling using the 2003 version of the Wilson-Devinney code was completed, yielding the basic parameters. The period appears to be constant, but further monitoring is highly desirable. Reference to zero age main sequence values in Cox (2000) indicates that both stars are evolved. Tables from Schaller et al. (1992) suggest an age of 3.17 Gy.
