Abstract:
This paper presents new complete uvby light curves of the late-type
detached eclipsing binary BH Vir (G0V + G5V, P=0.81687099d). This
binary system has been observed during four campaigns at the Calar
Alto Observatory (Almeria, Spain) and at the European Southern
Observatory (La Silla, Chile). This observations are part of a 6 year
uvby and H{beta} monitoring program of low mass eclipsing binaries
which main objective is to provide accurate absolute astrophysical
parameters for late-type main sequence stars. 1585 points spreaded
over the binary period and covering both eclipses are given. The
internal accuracy of the standard photometry measured as the mean RMS
of the differences between standard value and observed value for the
standard stars observed along the program is quoted in a few
millimagnitudes. Detailed analysis of BH Vir, based on these light
curves, will be published separately.
