Systematic search for members of the Hyades supercluster. VI. The lower main sequence.

From a complete sample of stars with visual magnitude brighter than 15 and annual proper motion larger than 0.5 arcsec, 50 members of the Hyades Supercluster have been identified by their proper motion. The resulting main sequence is represented, for M_bol > +5.5 mag, by M_bol = 4.51+4.31(R-I) with a dispersion of 0.15 mag. The supercluster stars may represent 15% of the star density near the Sun. Two incomplete samples of red dwarfs, formed by Vyssotsky and by Weis, are also examined for supercluster stars and add 34 members.
