Description

CW Eri is a double lined spectroscopic binary star. Since the two components are well detached, it is possible to derive absolute elements with high accuracy. Hejlesen, 1980, has calculated evolutionary tracks for stars of different chemical composition. In his log g - log Tsub(e) - graphs isochronic lines are given which allow for an age determination of binary stars. For CW Eri it is evident, that the components are lying on the respective evolutionary tracks according to their masses and that the isochronic line for 1.5 x 109 years fits both stars. (Auth.)
