Title: Magnetar powered superluminous supernovae
Date (JST): Wed, Nov 11, 2015, 15:40 - 16:40
Place: Seminar Room A
Abstract: Superluminous supernovae (SLSNe) have only recently been detected. They show a factor 10 to 100 times brighter than normal core-collapse SNe. The physical origins of the extreme luminosity emitted remains speculative.

One popular mechanisms invoked to explain SLSNe is that a magnetar is formed by the collapse of a massive star. The magnetar is a strongly-magnetized, rapidly-rotating neutron star that lose rotational energy via magnetic dipole radiation. That energy provides the extra kick and luminosity. We can study the effect of the shock wave propagation through the envelope with the spindown of the magnetar as the central engine. In this talk I shall comment on our progress to understand these peculiar objects by applying a radiative hydrodynamic code which allows to constrain the magnetar properties through fitting of the observed light curve.
