Is the metal contribution to the astrophysical opacity incorrect
Description
Numerical tests by Simon have indicated that an arbitrary increase in the metal (atomic number Z>2) contribution to the opacity by a factor of 2 to 3 leads to Cepheid models that, in some aspects, are in better agreement with observations than models using the standard opacity. We show that such a large increase in opacity is incompatible with atomic physics
