This book was released on 2012-12-06 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: IAU Symposium 101, Supernova Remnants and Their X-ray Emission, was held on the Island of San Giorgio, Venice, 30 August - 2 September 1982. It was co-sponsored by the National Research Council, Italy, the University of Padua, the Observatory of Padua, and the International Astronomical Union, and was hosted by the Cini Foundation. The contents of this volume show the wide range of disciplines that are involved in supernova remnant research. Many new results were presented, not only from the X-ray observations from the Einstein Observatory but also from observations at optical and radio wavelengths. This has led to the stimulation of theoretical work, much of which attempts to accommodate in a more unified way all of these observations. Research on supernova remnants of all ages was reported. Perhaps the most impressive part of all this work is the way in which observations at all wavelengths have extended well outside the Galaxy to other members of the Local Group and beyond. The Symposium was attended by scientists from 15 countries. Twenty five invited papers and sixty-eight shorter contributions were presented during the 4-day meeting. Thirty-three of these shorter contributions were presented in poster sessions. This volume contains almost all (89) of those contributions. They are followed by discussions which took place after each verbal presentation. Since the availability of the discussions was left to the individual contributors, they are not complete, but those contained in this volume convey some idea of the nature of the exchanges.

Available in PDF, EPUB and Kindle. Book excerpt: Neutron stars are invaluable tools for exploring stellar death, the physics of ultra-dense matter, and the effects of extremely strong magnetic fields. The observed population of neutron stars is dominated by the >1000 radio pulsars, but there are distinct sub-populations that, while fewer in number, can have significant impact on our understanding of the issues mentioned above. These populations are the nearby, isolated neutron stars discovered by ROSAT, and the central compact objects in supernova remnants. The studies of both of these populations have been greatly accelerated in recent years through observations with the Chandra X-ray Observatory and the XMM-Newton telescope. First, we discuss radio, optical, and X-ray observations of the nearby neutron stars aimed at determining their relation to the Galactic neutron star population and at unraveling their complex physical processes by determining the basic astronomical parameters that define the population---distances, ages, and magnetic fields---the uncertainties in which limit any attempt to derive basic physical parameters for these objects. We conclude that these sources are 1e6 year-old cooling neutron stars with magnetic fields above 1e13 Gauss. Second, we describe the hollow supernova remnant problem: why many of the supernova remnants in the Galaxy have no indication of central neutron stars. We have undertaken an X-ray census of neutron stars in a volume-limited sample of Galactic supernova remnants, and from it conclude that either many supernovae do not produce neutron stars contrary to expectation, or that neutron stars can have a wide range in cooling behavior that makes many sources disappear from the X-ray sky.
Download or read book Physics and Evolution of Supernova Remnants written by Jacco Vink and published by Springer Nature. This book was released on 2020-11-10 with total page 532 pages. 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: The theme of the conference held at the Institute of Astronomy in the summer of 1981 was 'Supernovae'. The topic was interpreted very broadly: observations in all wavebands were discussed, along with theories for the explosion mechanism and the light curves; there were papers on supernova remnants and pulsar statistics; other sessions dealt with the use of new techniques for improving supernova searches, and with the importance of supernovae for cosmogonic and cosmological studies. This book contains texts based on all the main review lectures, together with a number of shorter papers which describe new results presented at the conference. The Scientific Organising Committee, responsible for arranging the programme, consisted of J. Audouze, G. B. Brown, J. Danziger, F. Pacini, M. J. Rees (Chairman) and J. W. Truran. The conference was well attended, with over 100 visitors to Cambridge as well as many local participants. We are grateful to all those who helped with the practical organisation of the meeting, especially Dr Michael Ingham (Secretary of the Institute of Astronomy) and Mrs Norah Tate. We thank all the authors of the papers in this volume for the trouble they took in preparing written versions of their excellent lectures, and for the efforts they made to meet our ' final' deadl ine: we wish especially to thank Drs W. O. Arnett and J. M. Lattimer for help with the edi torial work.

Available in PDF, EPUB and Kindle. Book excerpt: This conference is a tribute to those astronomers who pioneered the investigation of this subject such a short time ago and who carried it through to its present state. (H. Arp, Concluding Remarks of the Conference) A previous conference, covering mainly the observational aspects of Supernovae, was held at the Haute Provence Observatory in September 1963. In the following ten years this field of research has considerably increased; it seemed, therefore, the right time to organize an international conference on Supernovae taking into account that in the meantime important discoveries, such as the Pulsars, had been made, and new techniques of observation were available. This book contains the proceedings of this conference held at Porto Cesareo (Lecce), Italy, during the period May 7 through 11, 1973. About one hundred participants from eighteen countries attended the conference. It was also the first attempt to hold an international conference in the Salento, the southernmost region of Apulia, in whose capital, Lecce, the newly founded Faculty of Sciences of the University of Lecce is located. The program of the conference included the results and techniques of Supernova surveys, photometric and spectral studies, statistics of Supernovae, Supernova Rem nants, and finally, theories on Supernovae and Supernova Remnants.

Download or read book Supernovae written by David N. Schramm and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supernovae are among the most exciting things occurring in the universe. Much recent research has concentrated on phenomena related to supernovae. For example, the origin of the cosmic rays and the origin of the bulk of the heavy elements seem to be closely associated with the phenomenon of supernovae. With the discovery of the pulsar in the Crab, it seemed clear that supernovae were also intimately as sociated with the formation of neutron stars and perhaps even black holes. The purpose of the conference, of which this volume contains the proceedings, was to bring together the leaders of supernova re search, each of whom has concentrated on different aspects of the problem, to try to form a coherent picture both observationally and theoretically of our current understanding of supernovae. In so doing, key invited talks were presented on the light curves of super novae, both observationally and theoretically; on the possible uses of supernovae, for example in determination of the Hubble Constant; on the formation and evolution of supernova remnants, again both ob servationally and theoretically. The possibility that supernovae might explain quasars was also presented. A review of the current status of statistics of supernovae was presented, giving the rate at which they go off and the implications with regard to what mass stars are the progenitors for supernovae. Again, this was presented both from the observational point of view and from the theoretical stellar evolution point of view.

Download or read book Supernovae and Gamma Ray Bursters written by Kurt Weiler and published by Springer. This book was released on 2008-01-11 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the dawn of mankind, observers of the sky have wondered at the sudden appearance of new stars on the seemingly unchanging heavens and, for at least 2000 years, have recorded these phenomena in their annals and archives. Even in more modern times, since the discovery of SN1885A in S Andromeda which ?gured in the important “island universe” discussions of the 1920’s, the puzzle of supernovae (SNe) has played an important role in astrophysics. Only with the seminal work of Fritz Zwicky and Walter Baade in the 1930’s did we begin to understand the di?erences between novae and SNe and the importance of SNe as the fonts of energy for the interstellar medium and as drivers of chemical evolution in galaxies. As recently as the 1940’s and 1950’s the early days of radio astronomy were heavily in?uenced by the familiar names of Cassiopeia A and Taurus A, two young supernova remnants, and two Nobel prizes have been awarded for discovery and study of a related phenomenon, pulsars. In spite of the great age of the study of SNe, since at least the Chinese records of SN185and probably earlier, the ?eld is, in fact, very young having only attracted a large devoted following since the spectacular Type II SN1987A in the Large Magellanic Cloud, the ?rst naked-eye SN in more than 400 years.
