Scientific paper

We present our analysis of longslit spectrophotometric data for a sample of ring galaxies. A detailed calculation of the radial variation of chemical abundances is used to examine the star formation history and possible collisional nature of these systems. We focus our attention on Arp 10, a peculiar ring galaxy, which exhibits an azimuthal variation of the star formation rate along the ring. Such a behavior is consistent with a collisionally induced density wave. We estimate the kinematics inferred from the spectra and present a plausible scenario of the evolution of the galaxy.
