The brightest stars in three irregular dwarfs around M 81.
KARACHENTSEV I.D., TIKHONOV N.A. and SAZONOVA L.N.
Abstract (from CDS):
B, V, R photometry of the brightest stars of DDO 53, VIIZw 403, and DDO 82 has been obtained with a CCD with the 6-m telescope. Taking the three brightest blue stars as a distance indicator yields the following distance moduli: 27.44mag for DDO 53, 27.41mag for VIIZw 403, and 28.26mag for DDO 82 with a 1σ error of about 0.4mag. Therefore all three dwarf irregulars are members of M 81 group.
