Astrophysics Aims and scope

Abstract

The distribution of B stars in the vicinity of nine southern, long-period (P > 11 days) Cepheids is studied on the basis of U, B, V data. The parameters Q, the normal color indices (B — V)0 and (U — B)0, the color excesses E(B — V), the spectral types, and the distance moduli of these stars are determined.
