Planetary nebulae and the galactic temperature gradient. (1986). Revista Mexicana De Astronomía Y Astrofísica, 12(1), 249-256. https://astronomia.unam.mx/journals/rmxaa/article/view/1986rmxaa..12..249m
Abstract
Galactic electron temperature gradients derived both from H II regions and planetary nebulae are studied. The effects of (1) systematic variations of the central star temperature, (2) dust grains, and (3) heavy-element abundance gradients on the electron temperature are considered. It is concluded that the heavy elements are the main responsible for the temperature gradient, and an estimate is made of the galactic O/H gradient.Similar Articles
