Strongly metal deficient planetary nebulae. (1990). Revista Mexicana De Astronomía Y Astrofísica, 21(1), 517. https://astronomia.unam.mx/journals/rmxaa/article/view/1990rmxaa..21..517m
Abstract
The authors study a group of planetary nebulae of type II with extremely low abundances of heavy elements. It is concluded that their central stars have masses lower than expected from most stellar evolution calculations.Similar Articles
