Evolution of H II regions. (1987). Revista Mexicana De Astronomía Y Astrofísica, 14(1), 463-473. https://astronomia.unam.mx/journals/rmxaa/article/view/1987rmxaa..14..463d

Abstract

The influence of the evolution on general properties of the H II regions is analyzed. The problem of the parametricity, the line ratios generally used as metallicity indicators, and the H II regions as distance calibrators are particularly discussed. Existing determinations of age in the LMC, SMC, and BCG are reviewed. An analysis of radio data on VH+ and VHe+ to determine ages for H II regions of the Milky Way is presented. Finally, it is also discussed the new idea on the link between H II region evolution and nuclear activity in galaxies.
