Top panel: dark matter mass distribution of the satellite of UGC 8760 as a function of the distance from the satellite center. The black-dashed line shows the mass distribution as in the ICs while the black solid after t = 0.69 Gyr. Bottom panel: same as in the top panel but showing the mass distribution of the stellar component on the satellite. The dashed blue line marks the position of the stellar component half-mass radius. The stellar mass distribution does not change from the ICs to 0.69 Gyr.
