Dielectronic Recombination Rate Coefficients for H‐like through Ne‐like Isosequences of Mg, Si, S, Ar, Ca, Fe, and Ni

Abstract

We present distorted-wave calculations and analytic fits to the radiative recombination rate coefficients of bare to F-like isosequences of seven abundant astrophysical elements, including Mg, Si, S, Ar, Ca, Fe, and Ni. The fits are valid over a wide range of temperature, from 10-4 to 104 eV. Extensive comparisons with existing data are made.
