The case of NGC 6302: the impact of shocks in the derivation of nitrogen abundances
PJA Lago, RDD Costa… - Monthly Notices of the …, 2019 - academic.oup.com
High nitrogen abundance is characteristic of Type I planetary nebulae, as well as their highly
filamentary structure. In the present work, we test the hypothesis of shocks as a relevant …
