Evolution of the Sgr-like dwarf galaxy ID117435. First panel: distance of the dwarf from the host (ID117252) as a function of time. Second and third panels: mass of the dwarf in different mass scales. Fourth panel: evolution of the shape parameters (the axis ratios b/a, c/a and triaxiality T) and the rotation parameter f. Fifth panel: evolution of the g − r color, SFR, and metallicity Z. The vertical dashed lines in each panel mark the pericenter passages.
