Some critical remarks on quasi-static stellar evolution models.

Quasi-static stellar evolution has been tackled numerically as early as electronic data-processing entered the field of astronomical research some fifty years ago. Despite some improvements in the description of turbulence, opacities, or in the equation of state, the results presented by different authors still show a rather wide spread in results. This poster tries to provide some hints on the reasons of these discrepancies and tries to point at difficulties that may arise from using theoretical stellar evolutionary tracks for mass/age determination of observed stars.
