Developments and comparison of two denim opacity models

Local Thermodynamic Equilibrium (LTE) opacity codes have been developed at DENIM during the last years. JIMENA [1, 2]is an opacity code that solves self-consistently, for each temperature and density, the radial Dirac equation with a local spherically symmetrical potential. Very recently we have developed a new opacity code, called ANALOP, that uses an analytical potential [3], which can include density and temperature effects for atomic data calculations. Opacities are determined with these two codes for selected elements at different plasma conditions.
