Tables of the partition functions for nickel, Ni I - Ni X
We present extensive tables of the atomic partition function (APF) for nickel ions, Ni I - Ni X. Partition functions are given over wide range of temperature, 10^3 K < T < 10^6 K, and lowering of ionization energy (0.001 eV < LIE < 5.0 eV), both taken as independent variables. Our APF take into account all energy levels predicted by quantum mechanics, including autoionization levels. The tables can be applied for the computations of model stellar atmospheres and theoretical spectra over very wide range of spectral classes, from the coolest K-M dwarfs up to the hottest main sequence, giant, and white dwarf stars. This include also model spectra of supersoft X-ray sources and accr…
Tables of the partition functions for iron, Fe I -- Fe X
We present extensive tables of the Atomic Partition Function for iron ions, Fe I -- Fe X, and discuss details of the computational method. Partition functions are given in wide range of temperatures, 10^3 K < T < 10^6 K, and lowering of ionization energy (0.001 eV < LIE < 5.0 eV). Our APF take into account all energy levels predicted by quantum mechanics, including autoionization levels. The tables can be applied for the computations of model stellar atmospheres and theoretical spectra over all existing spectral and luminosity classes.
