Further study of the high-velocity interstellar medium in the Carina nebula.

GARCIA B. and WALBORN N.R.

Abstract (from CDS):

We present new spectroscopic data for 12 stars in the field of Trumpler 16 and for 18 stars in Collinder 228, to analyze the behavior of the Ca II and Na I interstellar lines and to study the high radial velocity components. The purpose was to provide a finer map of the small angular scale changes in previously observed high-velocity components. We have found three striking new high-velocity profiles in Tr 16 and one probable case in Cr 228. However, the most important result is that as fainter members of the complex are observed, smaller fractions of high-velocity profiles are found, perhaps indicating that such profiles in the earlier spectral type, more massive stars are formed in their near vicinities, in an interaction between their stellar winds and surrounding interstellar material.
