Kinematics in Hickson Compact Group 90

Abstract

Using long-slit spectra observed at the VLT (ESO, Paranal) in May 2002, we studied the stellar kinematics in the core of the Hickson Compact Group 90. The line of sight velocity distribution (LOSVD), the velocity dispersion profiles and the Hermite moments h3,h4 along two slit positions are presented. The comparison with previous results is discussed. For kinematical analysis we used the parametrization for the LOSVD given in van der Marel et al. (1993).
