Core-collapse supernovae powered by magnetars
In the last decade, numerous super-luminous supernovae (SNe) have been discovered, with time-integrated luminosities up to 10-100 times greater than their `standard' counterparts. Here, I will discuss the basic properties of standard core-collapse SNe and the mechanisms by which their luminosity may be boosted. I will then focus on magnetar-powered SNe and discuss the results from numerical simulations of their light curves and spectra, together with a comparison to a few spectacular observations recently reported. Although rare, these super-luminous SNe capture the extremes of stellar evolution and stellar explosions, offering a critical look on the physics of massive stars.
