Fig. 3


Blue curve: evolution of the star formation rate of the dwarf galaxy shown in Figs. 1 and 2. The black curve is for the same model-A dwarf run in isolation. The star formation rate in the tidal tail within 1 kpc of the position of the satellite is shown with the red dashed curve, and constitutes a significant fraction of the total SFR in the system around the time of the merger. The satellite is completely disrupted after 2.5 Gyr, but its effects on the SFR are longlasting. The pericentre passages of the satellite are indicated by the black arrows.
