Scientific paper
The paper contains average values of radii, masses and mean densities determined for stars of given spectral types and luminosity classes. These values have been calculated on the basis of data from a catalog of parameters for eclipsing binaries (Brancewicz and Dworak, 1980). Results are presented in tables and diagrams. Diagrams which present radius-mass relation and mass-luminosity relation are also given. For the first time the mass-luminosity relation has been determined for subgiants (luminosity class IV).
