Resumen:
The purpose of these 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 Hip- parcos 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.
