Radial abundance gradients from planetary nebulae at different distances from the galactic plane. (2015). Revista Mexicana De Astronomía Y Astrofísica, 51(2), 165. https://astronomia.unam.mx/journals/rmxaa/article/view/2015rmxaa..51..165m
Abstract
We studied the variations of the radial O/H abundance gradients from planetary nebulae (PN) located at different distances from the galactic plane. In particular, we determined the abundance gradients at different heights from the plane in order to investigate a possible gradient inversion for the objects at larger distances from the plane. We considered a large sample of PN with known distances, so that the height relative to the galactic plane can be obtained and with accurate abundances, so that the abundance gradients can be determined.Similar Articles
