Resumen:
The purpose of this project is to verify if some relation exist between chemical abundances of some critical elements and the age of the stars. We selected HgMn stars in different clusters and field stars with data in the Hipparcos catalog to provide the correct position in the HR diagram. In these report we show some results obtained analizing the possible trends observed in the chemical abundance vs age relation for 4 sample stars: HD 129174, HD 186122, HD 78316 and HD 53244. The observations were done with the CASLEO EBASIM spectrograph between the years 2007 and 2010.
