Abstract
The ESTA activity under the CoRoT project aims at testing the tools for
computing stellar models and oscillation frequencies that will be used
in the analysis of asteroseismic data from CoRoT and other large-scale
upcoming asteroseismic projects.
Here I report results of comparisons between calculations using
the Aarhus code (ASTEC) and two other codes, for models that include
diffusion and settling.
It is found that there are likely deficiencies, requiring further study,
in the ASTEC computation of models including convective cores.
