The link between internal velocities in Galactic H II regions and the extragalactic H II regions. (1989). Revista Mexicana De Astronomía Y Astrofísica, 18(1), 99-103. https://astronomia.unam.mx/journals/rmxaa/article/view/1989rmxaa..18...99o
Abstract
The relation between the size and the internal velocities of Giant Extragalactic H II Regions (GEHR) has been compared with the proposed relation in Galactic H II Regions. The author has used the results of studies of the internal motions of eight Galactic objects to determine the internal velocities that would be determined had they been observed at the same spatial resolution. The author finds that the GEHR Hα isophotal diameters are ten times larger than their Galactic counterparts at the same internal velocity. This size difference indicates that the GEHR are actually conglomerates of multiple H II regions.Similar Articles
