Photoionization model for the emission of the Crab filaments, and their spread in composition

Journal Article · · Sov. Astron. Lett. (Engl. Transl.); (United States)
OSTI ID:6066426
;
Photoionization models are worked out for three groups of Crab Nebula filaments whose spectra typify the diverse emission-line intensity ratios measured in individual condensations. In each case the computed intensities match the values observed. The filaments exhibit a genuine spread in composition. 17 references.
