Scientific paper

The radial velocity and light curve of BE UMa have been studied to
determine the physical parameters of the stellar components. The authors
find that the primary is a very hot subdwarf which has a large heating
effect on a cool secondary, whose magnitude and radius both indicate
that it is an evolved subgiant.
