Gradientes de abundancias en la nebulosa planetaria A78. (1987). Revista Mexicana De Astronomía Y Astrofísica, 14(1), 528-533. https://astronomia.unam.mx/journals/rmxaa/article/view/1987rmxaa..14..528m
Abstract
New bidimensional spectroscopic observations of A78 allow the authors to determine the He, O, Ne, and N abundances and their variations along the nebula. A clear overabundance of these elements is found in the central region of the nebula, suggesting different nebular ejections of material processed in the stellar interior and dredged-up subsequently to the envelope.Similar Articles
