New opacity tables for asteroseismology
Sylvaine Turck-Chièze (CEA/Saclay), the OPAC team

Two new opacity tables are now available for stellar use. They have been computed respectively by the french OPAS team (Blancard et al. 2012) for the solar applications and by the Los Alamos team (Colgan et al. 2015, 2016) for stellar general use. The calculations leading to these tables have been studied in details by the OPAC consortium during the last 5 years. They have been partially checked by experiments and through detailed calculation comparisons (Bailey et al. 2015, Turck-Chièze et al. 2015, 2016). Some of them could be checked also thanks to coming future experiments (Lepennec et al. 2015) on large laser facilities (OMEGA, NIF, LMJ). The poster will summarize the different steps of validation of these calculations and discuss the limits of the present or past calculations.
