Stellar kinematic groups are kinematical coherent groups of stars that mighthave a common origin. These groups are dispersed throughout the Galaxy overtime by the tidal effects of both Galactic rotation and disc heating, althoughtheir chemical content remains unchanged. The aim of chemical tagging is toestablish that the abundances of every element in the analysis are homogeneusamong the members. We study the case of the Hyades Supercluster to compile areliable list of members (FGK stars) based on our chemical tagging analysis.For a total of 61 stars from the Hyades Supercluster, stellar atmosphericparameters (Teff, logg, xi, and [Fe/H]) are determined using our code calledStePar, which is based on the sensitivity to the stellar atmospheric parametersof the iron EWs measured in the spectra. We derive the chemical abundances of20 elements and find that their [X/Fe] ratios are consistent with Galacticabundance trends reported in previous studies. The chemical tagging method isapplied with a carefully developed differential abundance analysis of eachcandidate member of the Hyades Supercluster, using a well-known member of theHyades cluster as a reference (vB 153). We find that only 28 stars (26 dwarfsand 2 giants) are members, i.e. that 46% of our candidates are members based onthe differential abundance analysis. This result confirms that the HyadesSupercluster cannot originate solely from the Hyades cluster.
