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

Figure 7

Projected density (a) and velocity dispersion (b) profiles for satellites evolved in Orb1 and Orb4 for a longer time interval: 𝑡∼11 Gyr, instead of the fiducial 𝑡∼6 Gyr. Notice for Orb4 that, as mass depletion proceeds further, the spatial and kinematical segregation between 𝐶₁ and 𝐶₂ is increasingly erased.
