Abstract
Observations on the 6-m telescope in the Hα line and in the continuum are reported for 10 dwarf companions of the galaxy M31: And I, And II, And III, And V, And IX, And X, Cass dSph, Peg DSph, NGC147, NGC221, and one irregular dwarf galaxy in the background, And IV. All the observed companions of M31 have current star formation rates (SFR) on the order of or less than 10−6 M⊙ /yr. On a “star formation rate-neutral hydrogen mass” diagram for galaxies in the local volume, the dwarf spheroidal companions of Andromeda lie in the region of extremely low values for these parameters.
