Query: Radiative Accelerations in Stellar Evolution   A brief review of various methods to calculate radiative accelerations for
stellar evolution and an analysis of their limitations are followed by
applications to Pop I and Pop II stars. Recent applications to Horizontal
Branch (HB) star evolution are also described. It is shown that models
including atomic diffusion satisfy Schwarzschild's criterion on the interior
side of the core boundary on the HB without the introduction of overshooting.
Using stellar evolution models starting on the Main Sequence and calculated
throughout evolution with atomic diffusion, radiative accelerations are shown
to lead to abundance anomalies similar to those observed on the HB of M15.
