Space motions of galactic G- and K-type stars
Spectra of 912 G- and K-type stars in six galactic directions have beensecured. The relevant space motions of the stars, subdivided intodistance groups, have been derived; these show no significant departuresfrom the mean motion of nearby stars. The velocity dispersions, ingeneral, indicate that these (mainly giant) stars are moderately old.The dispersion in u is lower than that for nearby stars, and thesignificance of this result is discussed.
