Some remarks on metallic-line stars

It Is shown that the photoelectric (B-V) colors of the metallic line stars are correlated with the spectral types derived from the hydrogen lines. Consequently these stars can be grouped into several physically similar groups. The discrepancies different absolute magnitude determinations made in the...
