Available in PDF, EPUB and Kindle. Book excerpt: Written by a leading expert, this monograph presents recent developments on supernova remnants, with the inclusion of results from various satellites and ground-based instruments. The book details the physics and evolution of supernova remnants, as well as provides an up-to-date account of recent multiwavelength results. Supernova remnants provide vital clues about the actual supernova explosions from X-ray spectroscopy of the supernova material, or from the imprints the progenitors had on the ambient medium supernova remnants are interacting with - all of which the author discusses in great detail. The way in which supernova remnants are classified, is reviewed and explained early on. A chapter is devoted to the related topic of pulsar wind nebulae, and neutron stars associated with supernova remnants. The book also includes an extended part on radiative processes, collisionless shock physics and cosmic-ray acceleration, making this book applicable to a wide variety of astronomical sub-disciplines. With its coverage of fundamental physics and careful review of the state of the field, the book serves as both textbook for advanced students and as reference for researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This conference is dedicated to supernova remnants in their earliest phase of evolution. Its main goals are to provide an observational overview, particularly in light of recent advances, and then to set the observations in context by highlighting a number of physical processes that are important in young supernova remnants and also by examining a few specific remnant details.

Available in PDF, EPUB and Kindle. Book excerpt: Young supernova remnants such as Tycho, Kepler, and Cas A generally show a circular, clumpy shell near the outer boundary in both radio and X-ray emission. The magnetic field in the radio shell has been inferred to be in the range of $10sp{-4}sim10sp{-3}G$ by the minimum energy requirements. The detailed polarization studies reveal that the magnetic field in the shell exhibits a cellular pattern with a net radial orientation. In this thesis, attempts are made to explain the mechanism for the origin of strong radio emission from young supernova remnants by modeling the interaction between the ejecta and the interstellar medium. The Rayleigh-Taylor instability near the contact interface between the ejecta and the shocked ambient medium is studied in great detail by means of two- and three-dimensional MHD simulations. It is shown that the Rayleigh-Taylor instability model produce the thick clumpy radio shell as well as clumpy X-ray shell. The amplified magnetic field due to the Rayleigh-Taylor and Kelvin-Helmholtz instabilities is indeed strong and radial although the field strength is sensitive to the numerical resolution. However, the polarized magnetic field from the simulation is found to be dependent on the viewing angle because of the undisturbed large scale magnetic fields near the outer shock. To reconcile this result, the magnetic field in an ambient medium is required to be disordered on large scale, or an extra mechanism is required to randomize the large scale field if the ambient magnetic fields are ordered on a few parsec scale. The high degree of fractional polarization with a radial direction of magnetic fields in "rims" of Tycho's supernova remnant cannot be solved by the Rayleigh-Taylor instability model. In order to attack the unsolved problems by the Rayleigh-Taylor instability model, an assumption of uniform medium is relaxed to investigate the effect of cloudy medium. The cloudy medium model is found to produce the dominant radial magnetic fields in the mixing region overall with a larger fractional polarization near the outer shock. The total intensity is found to be strongly correlated with the polarized intensity which implies that the ordered magnetic fields are more responsible for the radio emission. The radio luminosity is significantly enhanced by the clouds encounter while the effect on X-ray luminosity is less significant. This model is a strong candidate for the mechanism which is responsible for the origin of many radio features in young supernova remnants.

Available in PDF, EPUB and Kindle. Book excerpt: After the supernova shock wave has swepted up about 8 to 10 stellar masses of interstellar material, the SNR structure is well described by blast wave theory. In fact, both numerical calculations of the early phases and small scale, laboratory simulations show transition to blast wave at 8 to 10 masses. In hindsight, we now know that the transition region between the photosphere (roughly 10−9 g/cm3) and the circumstellar medium (10−24 g/cm3) plays a crucial role. The shock wave is strongly accelerated down the density gradient, putting the shocked material behind into free expansion. When the shock encounters circumstellar material, it begins to decelerate. A second, reverse shock propagates into the stellar material that plows into the shocked circumstellar gas. All this happens on a timescale of days. The first attempts to include a description of the outer stellar envelop were aimed at analysis of the uv and X-Ray bursts produced when the shock wave reaches the photosphere. Falk and Arnett terminated their calculations before the shock reached the circumstellar gas. Chevalier mentions a reverse shock forming early but did not go into any details. We noticed and described the double-shock structure but, in hindsight, lacked sufficient resolution to produce the detailed structure between the shocks. Chevalier derived a similarity solution for the intershock region. In this paper we describe very high resolution calculations which reproduce and confirm the Chevalier similarity solution.
