The Distribution of Molecular Hydrogen in Planetary Nebulae
Published online by Cambridge University Press: 04 August 2017
Abstract
A correlation has been found between strong molecular hydrogen emission and the morphological type of a planetary nebula. Those with an equatorial toroid and bipolar extensions have H2 1−0 S(1) stronger than Brackett γ. H2 maps of several objects, and NGC 2346 in particular, are consistent with a fast stellar wind interacting with an anisotropic medium.
