SV Cen reveals its mystery

Abstract

Our very-first high resolution spectra of SV Cen close binary system obtained in the H alpha line reveal its absorption and emmision components, changing with orbital phase. An accretion disk surrounding the component eclipsed at the primary minimum is the most plausible explanation of this complex structure.Comment: To appear in ASP Conference Series special issue: "Binaries: Key to Comprehension of the Universe
