Abstract

Complete uvby light curves of the detached triple-lined late B-type eclipsing binary V906 Scorpii, secured from 1987 to 1991, are presented. A detailed photometric analysis based on these observations and on new spectroscopic material yields accurate masses and radii (errors ≲2%) for the components, confirms that the system is a member of NGC 6475 (Messier 7), and is published separately (Alencar et al. 1997).
