The Catalog of HgMn Stars

We compare these data to the previous compilation by Smith. We confirm the main trends of the abundance peculiarities, namely the increasing overabundances with increasing atomic number of heavy elements, and their large spread from star to star.

For all the measured elements, we have looked for correlations between abundances and effective temperature (T_eff_). In addition to the known correlation for Mn, some other elements are found to show some connection between their abundances and T_eff_. We have also checked if multiplicity is a determinant parameter for abundance peculiarities determined for these stars.
