Reverberation of the Vela PULSAR WIND NEBULA
Письма в Астрономический журнал: Астрономия и космическая астрофизика, 2023Transonic (withMach numberMs 1) motion of a pulsar relative to the external medium canhelp its compact pulsar wind nebula develop a double-torus X-ray morphology. The double-torus structurecan reverberate as a whole under the dynamic pressure of the external flow. For a flow aligned with thesymmetry axis of the nebula, the response of the double-torus

TIME-DEPENDENT MODELING OF PULSAR WIND NEBULAE [PDF]
Astrophysical Journal, 2013 A spatially independent model that calculates the time evolution of the electron spectrum in a spherically expanding pulsar wind nebula (PWN) is presented, allowing one to make broadband predictions for the PWN's non-thermal radiation. The source spectrum of electrons injected at the termination shock of the PWN is chosen to be a broken power law.

Theory of Pulsar Wind Nebulae [PDF]
AIP Conference Proceedings, 2008 Our understanding of Pulsar Wind Nebulae (PWNe), has greatly improved in the last years thanks to unprecedented high resolution images taken from the HUBBLE, CHANDRA and XMM satellites. The discovery of complex but similar inner features, with the presence of unexpected axisymmetric rings and jets, has prompted a new investigation into the dynamics of ...

Modelling Jets, Tori and Flares in Pulsar Wind Nebulae [PDF]
Space Science Reviews, 2017 In this contribution we review the recent progress in the modelling of Pulsar Wind Nebulae (PWN). We start with a brief overview of the relevant physical processes in the magnetosphere, the wind-zone and the inflated nebula bubble.

Discovery and Characterization of Superefficiency in Pulsar Wind Nebulae [PDF]
Astrophysical Journal Letters, 2018 Abstract We numerically study the radiative properties of the reverberation phase of pulsar wind nebulae. Reverberation brings a significant evolution in a short period of time. We show that even the Crab Nebula, associated with the more energetic pulsar of the sample that we consider, has a period in its future time evolution where the ...

Pulsars and Pulsar Wind Nebulae
2019When heavy stars have burned all their nuclear fuel, neutron degeneracy pressure is the last force able to halt their collapse into a black hole. The sudden stop of the free-fall collapse leads to a rebound of the infalling matter triggering an outward shock that blows up the star envelope and powers a Type II supernova.
