The chemodynamical evolution of spherical multi-component self-gravitatingmodels for isolated dwarf galaxies is studied. We compare their evolution withand without feedback effects from star formation processes. We find thatinitially cuspy dark matter profiles flatten with time as a result of starformation, without any special tuning conditions. Thus the seemingly flattenedprofiles found in many dwarfs do not contradict the cuspy profiles predicted bycosmological models. We also calculate the chemical evolution of stars and gas,to permit comparisons with observational data.
