Evolving star formation rates during the simulations. In a) the star formation rates of the three model galaxies evolving in vacuum are shown, which are at about 1.5   M_⊙   yr^-1 for all galaxies. In b) and c) the star formation rates of the galaxies undergoing ram-pressure stripping are plotted, with an ICM density of b) 10^-28   g   cm^-3 and c) 10^-27   g   cm^-3. Already with a low ram pressure, the star formation is enhanced by a factor of two while with a high ram pressure the enhancement can reach a factor of 4 after the first interaction of the galaxies with the ICM. Clearly, a bulge suppresses the star formation rate. In d) and e) the star formation rate of model galaxy “1nb” undergoing ram-pressure stripping, flying with different inclination angles with respect to the ICM is shown. The star formation is suppressed if the galaxy is flying edge-on in case of high ram pressure. When a low ram pressure is acting on the galaxies, the inclination angle has almost no influence, the star formation rate is not affected.
