Currently, with the most exhaustive surveys of transient phenomena in the sky, new super-luminous supernovae (SLSNe) have been reported. The increase in the population of the known events makes the problem of establishing (probably depending on the sub-type) what is the mechanism capable of making them shine with peak luminosities far exceeding (10 to 100 times) those of normal supernovae. It has been proposed that some of these SLSNs can be explained by the formation via gravitational collapse of a highly magnetized neutron star, or magnetar, which initially rotates with a period of the order of milliseconds.We have incorporated in our 1D hydrodynamic simulations the effect of the sustained energy injection of a magnetar. The variation of the properties of the ejecta and the magnetar introduces changes in the light curve (rising time, maximum luminosity, width of the light curve). We show the most importantfeatures of our work in progress, and that our models can explain some observed light curves.
