Diagnostic Diagrams for Planetary Nebulae and Symbiotic Stars
Published online by Cambridge University Press: 07 August 2017
Abstract
One of us (Gutiérrez-Moreno 1988) presented some time ago a preliminary version of two diagrams for separating planetary nebulae (PN) from symbiotic stars (SS); tnese diagrams are based on the strength of [O III] lines λλ4363, 5007. Now a new version is presented, which includes more objects and uses measured total intensities corrected by reddening.
