Description

Absolute parameters of 18 W Ursae Majoris systems have been collected. The evolutionary status of these systems is discussed on the basis of the mass-radius and mass-luminosity diagrams. It is concluded that majority of binaries from analysed sample lie close to ZAMS line on both diagrams. Four systems seem to be evolved and to have unexpectedly large temperatures as for their masses. 52 refs., 2 figs., 3 tabs. (author)
