Temperature Variations and Abundance Determinations in Planetary Nebulae
arXiv:astro-ph/0203141
Abstract
It is argued that an important fraction of PNe present large temperature variations that are not due to observational errors nor to incomplete atomic physics. Seven possible causes for these variations are reviewed, one of them is presented for the first time.
