irts. Thes suggest the presence of either recent ongoing and/or prolonged star formation episodes, shedding new light on the evolution of these systems.<i>Aims. <i/>We aim at understanding the evolutionary path[s] of these early-type galaxies and the mechanisms at the origin of their UV-bright structures. We investigate with 8 pick_search"sudi>velengh the link between the inner and outer galaxy regions of a set of 11 early-type galaxies that were selected because of their nearly passive stage of evolution in the nuclear region.<i>Methods. <i/>This paper, second of a series, focuses on the information coming from the comparison between UV features detected by <i>Swift<i/>-UVOT, which trac8 pick_search"sudi>star form the galaxy optical structure, which maps older stellar populations.
