Abstract

The Hipparcos mission has made possible to constrain the positions of the nearby stars in the HR diagram with high accuracy. We reconsider the evolutionary status of the Am stars, as given by their position in the HR diagram; we discuss the measured abundance anomalies in function of the age and mass of the star.
