Descripción
We present results of narrow-band and broad-band optical CCD imaging together with intermediate-resolution spectroscopy of the Wolf-Rayet galaxy Mkn 8. Analysis of the morphology and kinematics of the object indicates that the strong star formation episode we are witnessing in Mkn 8 is the product of the interaction of two (or three) disk galaxies. The chemical abundances and abundance ratios measured in the brightest knots suggest that the interacting galaxies are chemically evolved gas-rich objects, perhaps late-type spirals.
