Context. We are investigating the star formation in galaxies of actively evolving Dorado group where, for a large fraction both early- and late-type galaxies, signatures interactions merging events revealed by optical radio observations. Aims. Our previous H α +[N II] study, probing ≈10 Myr timescales, suggested that is still ongoing early-type galaxies. In this work, we use far-UV (FUV) imagin...
