Helium and Oxygen Abundances in SMC Planetary Nebulae
Published online by Cambridge University Press: 25 May 2016
Abstract
In this work we report new high quality spectroscopic data for a sample of PNe in the SMC, aiming to derive physical parameters and chemical abundances, in particular to settle the question concerning the oxygen discrepancy found for type I planetaries with respect to stars and HII regions.
