H$\alpha$ kinematics of the isolated interacting galaxy pair KPG 486
  (NGC 6090)
  In optical images, the not amply studied isolated interacting galaxy pair KPG
486 (NGC 6090) displays similar features to the galaxy pair The Antennae (NGC
4038/39). To compare the distribution of ionized hydrogen gas, morphology and
kinematic and dynamic behaviour between both galaxy pairs, we present
observations in the H$\alpha$ emission line of NGC 6090 acquired with the
scanning Fabry-Perot interferometer, PUMA. For each galaxy in NGC 6090 we
obtained several kinematic parameters, its velocity field and its rotation
curve, we also analysed some of the perturbations induced by their encounter.
We verified the consistency of our results by comparing them with kinematic
results from the literature. The comparison of our results on NGC 6090 with
those obtained in a previous similar kinematic analysis made for The Antennae
highlighted great differences between these galaxy pairs.
