The ratio of total to selective absorption in the Carina OB2 association

Abstract:

Several previous studies in and around the Great Carina nebula (NGC 3372) have strongly indicated an abnormal interstellar extinction law with a high ratio of total to selective absorption R. In the present study, new UBV photometric data and accurate MK spectral-types of stars in the region of the Carina OB2 association are used to show that (1) Car OB2 is a genuine stellar association located at a distance of 3.2 kpc, and (2) the interstellar extinction law seems to be normal throughout most of the region. A representative value of R = Av/E(B - V) = 3.0 is derived for Car OB2 from the variable extinction method. © 1988 Kluwer Academic Publishers.
