Signatures of the non-Maxwellian ?-distributions in optically thin line spectra I. Theory and synthetic Fe IX?XIII spectra
Original language description
We investigate the possibility of diagnosing the degree of departure from the Maxwellian distribution using single-ion spectra originating in astrophysical plasmas in collisional ionization equilibrium. We find that it is possible to perform density diagnostics independently of kappa, with many Fe xi, Fe xii, and Fe xiii line ratios showing strong density-sensitivity and negligible sensitivity to kappa and temperature. We also tested different averaging of the collision strengths. It is found that averaging over 0.01 interval in log(E [ Ryd ]) is sufficient to produce accurate distribution-averaged collision strengths Upsilon(T,kappa) at temperatures of the ion formation in ionization equilibrium.
