The Effect of Tidal Stripping on Composite Stellar Populations in Dwarf Spheroidal Galaxies

Figure 3

Final projected view (arbitrary units) of the dark matter (black), metal poor (blue) and metal rich (red) stellar components for the models evolved in orbits 1–4 during  Gyr. Due to the different degree of tidal disruption experienced in each case, some satellites have turned more elliptical in shape in either one (Orb2) or both (Orb4) their stellar components. Satellites in orbits 1 and 4 remain still quite spherical as the progenitor model.
