Abstract:
To better understand the hot chemically peculiar group of HgMn stars,
we have considered a compilation of a large number of recently
published data obtained for these stars from spectroscopy. 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 (Teff). In addition to the known correlation for Mn,
some other elements are found to show some connection between their
abundances and Teff. We have also checked if multiplicity is a
determinant parameter for abundance peculiarities determined for these
stars. A statistical analysis using a Kolmogorov-Smirnov test shows
that the abundances anomalies in the atmosphere of HgMn stars do not
present significant dependence on the multiplicity.
Description:
This Catalogue of HgMn Stars is a compilation of the chemical
abundances determined by various authors since 1993 and before 2013,
for 106 stars identified as HgMn by these authors. The effective
temperatures, gravities, rotational velocities, microturbulent
velocities, as appearing in corresponding publications, are also
given. The selection criteria among the published measures are
explained in the paper. The abundances of HgMn stars have been
rescaled by these authors using the solar abundances given by Asplund
et al. (2009ARA&A..47..481A 2009ARA&A..47..481A). Object classifications are taken from
Simbad archive (see http://simbad.u-strasbg.fr/simbad/).
