Peimbert Física, Astronomía y Matemáticas Orion nebula) ISM: abundances Sun: abundances H II regions (M17 Galaxies: chemical evolution We discuss a chemical evolution model with Z-dependent yields that reproduces the O/H, C/H, and C/O gradients of the Galactic disk and the chemical history of the solar vicinity. The model fits the H, He, C, and O abundances derived from recombination lines of the H ii region M17 (including the fraction of C and O atoms embedded in dust); the protosolar H, He, C, O, and Fe abundances; and the C/O-O/H, C/Fe-Fe/H, and O/Fe-Fe/H relations derived from stars of the solar vicinity. The agreement of the model with the protosolar abundances at the Sun-formation time implies that the Sun originated from a well mixed ISM at a galactocentric distance of 7.6 ± 0.8 kpc. 2011 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57121297016 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.40
