IUE observations of the halo planetary nebula BB-1: the C, O and Ne abundances. (1993). Revista Mexicana De Astronomía Y Astrofísica, 27(1), 175-179. https://astronomia.unam.mx/journals/rmxaa/article/view/1993rmxaa..27..175p
Abstract
The authors present new high and low dispersion IUE observations of the halo planetary nebula BB-1 (PN G108.4-76.1). They have determined the C/H value to be 5.1×10-4. This object is among the PNe with the highest C/O and Ne/O ratios; its Ne/O ratio is 10 times higher than solar. The extreme enrichment of C and Ne imposes strong constraints on stellar evolution models of low-mass stars.Similar Articles
