Abstract
During last year’s analysis of FEROS spectra [1], we discovered that the triple system AO Vel with an eclipsing BpSi primary is in fact a remarkable quadruple system with ZAMS and PMS companions. The four stars form two spectroscopic binaries orbiting around each other in a wide orbit with a 41 yr period. For the first time, direct determination of the radius and the mass have been obtained for a BpSi star. We present here our recent study of chemical abundances of all four components using recent high-resolution, high signal-to-noise UVES spectra.
