  Stellar kinematic groups are kinematical coherent groups of stars that might
have a common origin. These groups are dispersed throughout the Galaxy over
time by the tidal effects of both Galactic rotation and disc heating, although
their chemical content remains unchanged. The aim of chemical tagging is to
establish that the abundances of every element in the analysis are homogeneus
among the members. We study the case of the Hyades Supercluster to compile a
reliable list of members (FGK stars) based on our chemical tagging analysis.
For a total of 61 stars from the Hyades Supercluster, stellar atmospheric
parameters (Teff, logg, xi, and [Fe/H]) are determined using our code called
StePar, which is based on the sensitivity to the stellar atmospheric parameters
of the iron EWs measured in the spectra. We derive the chemical abundances of
20 elements and find that their [X/Fe] ratios are consistent with Galactic
abundance trends reported in previous studies. The chemical tagging method is
applied with a carefully developed differential abundance analysis of each
candidate member of the Hyades Supercluster, using a well-known member of the
Hyades cluster as a reference (vB 153). We find that only 28 stars (26 dwarfs
and 2 giants) are members, i.e. that 46% of our candidates are members based on
the differential abundance analysis. This result confirms that the Hyades
Supercluster cannot originate solely from the Hyades cluster.
