Modeling the spectral evolution of PWNe inside SNRs

Understand

We present a new model for the spectral evolution of Pulsar Wind Nebulae inside Supernova Remnants.

• The model couples the long-term dynamics of these systems, as derived in the 1-D approximation, with a 1-zone description of the spectral evolution of the emitting plasma.
• Our goal is to provide a simplified theoretical description that can be used as a tool to put constraints on unknown properties of PWN-SNR systems: a piece of work that is preliminary to any more accurate and sophisticated modeling.
• In the present paper we apply the newly developed model to a few objects of different ages and luminosities.
