AO Velorum: a young quadruple system with a ZAMS eclipsing BpSi primary.

GONZALEZ J.F., HUBRIG S., NESVACIL N. and NORTH P.

Abstract (from CDS):

Using recent spectroscopic observations, we show that the triple system AOVel with an eclipsing BpSi primary is in fact a remarkable quadruple system formed by two double-lined spectroscopic binaries with components close to the ZAMS. All available data have been reanalyzed to derive proper orbital parameters for both binary systems and to calculate absolute parameters of the eclipsing system. For the first time, direct determination of the radius and the mass have been obtained for a BpSi star. The study of the physical parameters of this unique system is especially important since it can be used as a test of evolutionary models for very young stars of intermediate mass.
