Opal opacity
Webopacity is evaluated using configuration-average distorted wave calculations. The free–free opacity is obtained by interpolating between the Drude-like opacity and the … WebThe OPAL opacity model has been used to solve several long standing puzzles in astrophysics, through a better treatment of the metal contribution to stellar opacity. Direct experimental verification of the opacity models has also been pursued at LLNL using the NOVA laser. The comparisons between theory and experiment clearly demonstrate the …
