The XSTAR Atomic Database

摘要: We report on the XSTAR atomic database that contains a large quantity of rates for use in spectral modeling astrophysical plasmas. The includes energy levels, line wavelengths, radiative transition probabilities, electron impact excitation rates, photoionization cross section, recombination rate coefficients, ionization and fluorescence Auger yields. species considered are all ions H, He, C, N, O, Ne, Mg, Si, S, Ar, Ca, Fe, Ni. collects recent data from many sources including CHIANTI, TOPbase, ADAS, NIST, IRON Project. Two particular features incorporation sections Opacity Project levels every ion, state-specific rates. State-specific collisional three-body also included. collection is used to build excitation-ionization models each ion calculation their spectra densities up 1018 cm-3 temperatures between 100 109 K. In addition, model designed converge LTE under appropriate conditions. These implemented code v.2.
