Evidence of mass loss from a close binary system: The Hyades member eclipsing binary BD +16 516.
Abstract
It is shown that the Hyades member eclipsing binary BD + 160 516 must be the product of late evolution of an initial system composed of a 1.9 Me primary and a 0.4 Me secondary. The present evolved system being composed of a 0.8 Me K0V star on the main sequence and of a 0.7 Me hot white dwarf, it is argned that the evolution of such a system took place through both a mass exchange of 0.4 Me from the primary to the secondary and a mass loss of 0.8 Me, probably through a planetary-nebula phase. Key words: close binary systems - evolution - mass loss - planetary nebulae - white dwarfs
