A study of diffuse southern Ha nebulae

Gum, Colin Stanley


The result of a photographic survey for diffuse Ha emission nebulosities (HII regions) in the Southern Milky Way from galactic longitude 1+190° to 350° are given. A catalogue, which includes a number of new objects, lists positions and dimensions of 85 physically separate H II regions together with details of the exciting stars and their distance moduli when available. The faintest objects detected have n3=1, where n3 is the number of third level hydrogen atoms in a column 1 cm2 in...[Show more]
