Low density envelopes of southern H II regions. (1987). Revista Mexicana De Astronomía Y Astrofísica, 15(1), 125-132. https://astronomia.unam.mx/journals/rmxaa/article/view/1987rmxaa..15..125a
Abstract
Extended and low density ionized gas envelopes associated to some H II regions, have been studied in the H166α recombination line and the continuum at 1.4 GHz. From these observations, values of some physical parameters have been obtained. The observed H II regions are the following: RCW 49, G 338.4+0.0, G 331.5-0.1, W31, RCW 122 and RCW 38. In these regions the authors have observed a structure similar to other H II regions which consists of a small compact H II region with an extended low density envelope.Similar Articles
