Abstract

Copyright © 2018, arXiv, All rights reserved. The emission lines emitted from gaseous nebulae carry valuable information about the physical conditions and chemical abundances of ionized gases in these objects, as well as the interstellar reddening. We determine the electron temperature, the electron density, and the ionic abundances from the dereddened fluxes of collisionally excited lines (CEL) and recombination lines (RL) identified in nebular spectra (see e.g. Danehkar, Parker, and Ercolano (2013); Danehkar et al. (2014); Danehkar, Parker, and Steffen (2016); Danehkar (2018b)).
