This note presents theoretical color-magnitude diagrams (CMDs) and metallicity evolution for Galactic multipopulation models coupled to stellar evolution models for systems undergoing stripping and re-accretion of ambient material, called “open” systems in our recent studies (Valle et al. 2005, A&A, 435, 551). We show that the observables for such systems, in particular those related to the recovered star formation as a function of time, are ambiguous – systems with non-monotonic star formation rates can appear as either bursting systems or galaxies with a hiatus in the star formation.
Key words: galaxies: evolution / galaxies: interactions
