High-temperature behaviour of the helium-like K ALPHA G ratio: the effect of improved recombination rate coefficients for calcium, iron, and nickel
J. Oelgoetz, C. J. Fontes, H. L. Zhang +3
It is shown that above the temperature of maximum abundance, recombination rates into the excited states of He-like ions that are calculated using earlier, more approximate methods…

[O II] line ratios
Anil K. Pradhan, Maximiliano Montenegro, Sultana N. Nahar +1
Based on new calculations we reconfirm the low and high density limits on the forbidden fine structure line ratio [O II] I(3729)/I(3726): lim_{N_ e} --> 0} = 1.5 and lim_{N_ e} -->…
