Supernovae, Pulsars and Gamma-ray Bursts: a Unified Picture
A scenario is proposed that explains both the observed high pulsar velocities and extragalactic gammaray bursts (GRBs). The model involves an ultra-relativistic jet from a supernova (SN), that produces a GRB and its afterglow, whose characteristics are similar to an isotropic fireball GRB perhaps with some differences at late times in the afterglow once some significant transverse diffusion has...
متن کاملAsymmetric Supernovae, Pulsars, Magnetars, and Gamma-Ray Bursts
We outline the possible physical processes, associated timescales, and energetics that could lead to the production of pulsars, jets, asymmetric supernovae, and weak γ-ray bursts in routine circumstances and to a 1016 G magnetar and perhaps stronger γ-ray burst in more extreme circumstances in the collapse of the bare core of a massive star. The production of a LeBlanc-Wilson MHD jet could prov...
متن کاملRadio Supernovae Radio Supernovae
In this article I will briefly review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio light curves of nearby core-collapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby supernovae and their remnants. These later sec...
متن کاملSeparated before birth: pulsars B2020+28 and B2021+51 as the remnants of runaway stars
Astrometric data on the pulsars B2020+28 and B2021+51 suggest that they originated within several parsecs of each other in the direction of the Cyg OB2 association. It was proposed that the pulsars share their origin in a common massive binary and were separated at the birth of the second pulsar following the asymmetric supernova explosion. We consider a different scenario for the origin of the...
متن کاملGamma-Ray Pulsars
Gamma-ray photons from young pulsars allow the deepest insight into the properties and interactions of high-energy particles with magnetic and photon fields in a pulsar magnetosphere. Measurements with the Compton Gamma-Ray Observatory have led to the detection of nearly ten γ-ray pulsars . Although quite a variety of individual signatures is found for these pulsars, some general characteristic...
