Measuring nebular temperatures: the effect of new collision strengths with equilibrium and kappa-distributed electron energies
David C. Nicholls, Michael A. Dopita, Ralph S. Sutherland +2
In this paper we develop tools for observers to use when analysing nebular spectra for temperatures and metallicities, with two goals: to present a new, simple method to calculate…
Fine structure collision strengths and line ratios for [Ne V] in infrared and optical sources
Michael Dance, Ethan Palay, Sultana N. Nahar +1
Improved collisions strengths for the mid-infrared and optical transitions in Ne V are presented. Breit-Pauli R-Matrix calculations for electron impact excitation are carried out w…
Improved collision strengths and line ratios for forbidden [O III] far-infrared and optical lines
Ethan Palay, Sultana N. Nahar, Anil K. Pradhan +1
Far-infrared and optical [O III] lines are useful temeprature-density diagnostics of nebular as well as dust obscured astrophysical sources. Fine structure transitions among the gr…
