In this paper, we study how the dark matter density profiles of dwarf galaxies in the mass range 108-1010 M⊙ are modified by the interaction of the dwarf galaxy with neighbouring structures, and by the changing baryon fraction in dwarf galaxies. With this aim, and referring to an earlier paper by De...
