Descripción
A new uvby and H-beta monitoring program of low mass eclipsing binaries
is currently being carried out in the framework of a 5-yr observational
program which also involves radial velocity determinations. The scope of
this work is to provide very accurate absolute astrophysical parameters:
mass, radius, and effective temperatures, for main-sequence late-type
stars. One of the main goals is to improve the mass-luminosity relation
in the low and intermediate mass range. A second objective is to perform
accurate tests of the most recent grids of evolutionary models. This
program is complementary to that currently being implemented by the
Copenhagen group. In this contribution we present the photometric
preliminary results obtained for three of the systems included in our
long-term survey: BH Vir, ZZ UMa, and CR Cas for which primary eclipses
have been observed. Particular attention is paid to the determination of
reddening, distances, and radiative properties. A more detailed study
will be carried out when the light curves and radial velocity
measurements are completed.
