Scientific paper

The abundances of Na, Mg, and Al in three giants and four dwarfs in the Hyades open cluster have been derived from high-resolution, McDonald 2.7-m echelle spectra. These data are compared to the expected changes in surface composition of the giants as predicted by a stellar model generated with the Clemson-American University of Beirut stellar evolution code in order to investigate if the Hyades giants have undergone non-standard mixing. The preliminary results of our analysis are presented.
