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

| description |
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 2.8 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. This paper will be published elsewhere. |
