Pulsar Wind Nebulae and Their Supernovae
Roger A. Chevalier
Young supernova remnants that contain pulsar wind nebulae provide diagnostics for both the inner part of the supernova and the interaction with the surrounding medium, providing an…
Supernova Remnant and Pulsar Wind Nebula Interactions
Roger A. Chevalier
I review several topics in the structure of supernova remnants. Hydrodynamic instabilities in young remnants may give rise to the cellular structure that is sometimes observed, alt…
The Surroundings of Gamma-Ray Bursts: Constraints on Progenitors
Roger A. Chevalier
The association of a supernova with a gamma-ray burst (GRB 030329) implies a massive star progenitor, which is expected to have an environment formed by pre-burst stellar winds. Al…
Interactions between Pulsars, Pulsar Nebulae and Supernova Remnants
Roger A. Chevalier
The Crab Nebula is likely to be expanding into freely expanding supernova ejecta, although the energy in the ejecta may be less than is typical for a Type II supernova. Pulsar nebu…
Interaction Models for GRB Afterglows
Zhi-Yun Li, Roger A. Chevalier
We review interaction models for GRB afterglows, with an eye on constraining the nature of their progenitors and the geometry of explosion. Evidence is presented for two types of p…
Implications of the X-Ray Properties of Pulsar Nebulae
Roger A. Chevalier
A plausible model for the Crab Nebula is one in which a particle dominated, highly relativistic wind from the pulsar passes through a shock front in which the particles attain a po…
