Interaction of hot stars and of the interstellar medium. III. Excitation sources for small galactic nebulae.
Abstract
Summary. Evidence is presented for the presence of hot stars associated with a number of small galactic nebulae and probably responsible for their excitation. Thus, excitation mechanisms other than ultra-violet stellar radiation, as suggested by Terzian (1970) and Turner (1971) are not necessary. Key words: H ii regions - exciting stars
