COLUMN DENSITIES OF INTERSTELLAR GAS IN THE DIRECTION OF THE STAR-EPSILON ORI-(B0-IA)

Abstract

We have investigated the star epsilon Ori with IUE high resolution SWP spectrum in order to derive curve of growth and column densities of A1II, SiII, SII, FeII, NiII and ZnII. It has been possible to fit these ions on one empirical curve of growth with a velocity parameter b = 11 km s(-1) for the star studied.
