By comparing C/Ovalues observed in stars of the solar vicinity and Galactic H II regions with those predicted by chemical evolutionmodels for the Galaxy, which assume these observational yields, I conclude that the C abundances derived frompermitted lines are better than those derived from forbidden lines. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57112086 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.12 |
