Signatures of pulsars in the light curves of newly formed supernova remnants

Understand

We explore the effect of pulsars, in particular those born with millisecond periods, on their surrounding supernova ejectas.

• While they spin down, fast-spinning pulsars release their tremendous rotational energy in the form of a relativistic magnetized wind that can affect the dynamics and luminosity of the supernova.
• We estimate the thermal and non thermal radiations expected from these specific objects, concentrating at times a few years after the onset of the explosion.
• We find that the bolometric light curves present a high luminosity plateau (that can reach $10^{43-44}\,$erg/s) over a few years.
