| contents | Revised diagnostic diagrams for planetary nebulae H. Riesgo J. A. López Física, Astronomía y Matemáticas SM: PLANETARY NEBULAE Diagnostic diagrams of electron density-excitation for a sample of 613 planetary nebulae are presented. The present extensive sample allows the definition ofnew statistical limits for the distribution of planetary nebulae in the log [H/[S ii]]versus log [H/[N ii]], log [H/[S ii]] versus [S ii] 6717/6731, and log [H/[N ii]]versus [S ii] 6717/6731 planes. The diagrams provide a good representation ofthe ranges of physical conditions, indicated by these emission line ratios, present inplanetary nebulae during different evolutionary stages. 2006 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57142106 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) Num.1 Vol.42 |
