Stellar motions along I = 60 - 240 and I = 150-330 inhomogeneous frequency distribution of spectral types

Abstract


Applications of the x² test to the frequency distribution of spectral types show a slight predominance of A, F and G stars running approximately along I = 60 - 240 ; along the orthogonal direction, there seems to occur a preponderance of K and M stars.
