- Temperature variations and n+/o+ in the orion nebula II the collision strengths R. H. Rubin R. J. Dufour P. G. Martin G. J. Ferland J. A. Baldwin C. O. Ortiz D. K. Walter Física, Astronomía y Matemáticas ISM: IN ISM: ABUNDANCES ISM: H II REGIONS DIVIDUAL: ORION NEBULA We continue an investigation of electron temperature (Te), mean{square Tevariation (t2), and the N+/O+ abundance ratio. Our previous analysis of HSTspectra of the Orion Nebula used collision strengths for N+ by Sta ord et al. (1994).Here we examine the consequences of changing just these collision strengths by usingthose of Lennon & Burke (1994). Rather than utilize the standard analytical, lowelectron density (Ne) regime treatment for the analysis, we develop a numericaltechnique that is valid at any density. With Sta ord et al. collision strengths, wend the average Ne for the (N+, O+){zone is 7500 cm 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101008 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.10
