Book Description
This book presents the theory of the electrodynamic phenomena that occur in the magnetosphere of a pulsar. It also provides a clear picture of the formation and evolution of neutron stars. The authors address the basic physical processes of electron-positron plasma production, the generation of electric fields and currents, and the emission of radio waves and gamma rays. The book also reviews the current observational data, and devotes a complete chapter to a detailed comparison of this data with accepted theory and with some recent theoretical predictions. Tables containing the values of the physical parameters of all observed radio pulsars are also provided.

Book Description
Neutron stars are the most compact astronomical objects in the universe which are accessible by direct observation. Studying neutron stars means studying physics in regimes unattainable in any terrestrial laboratory. Understanding their observed complex phenomena requires a wide range of scientific disciplines, including the nuclear and condensed matter physics of very dense matter in neutron star interiors, plasma physics and quantum electrodynamics of magnetospheres, and the relativistic magneto-hydrodynamics of electron-positron pulsar winds interacting with some ambient medium. Not to mention the test bed neutron stars provide for general relativity theories, and their importance as potential sources of gravitational waves. It is this variety of disciplines which, among others, makes neutron star research so fascinating, not only for those who have been working in the field for many years but also for students and young scientists. The aim of this book is to serve as a reference work which not only reviews the progress made since the early days of pulsar astronomy, but especially focuses on questions such as: "What have we learned about the subject and how did we learn it?", "What are the most important open questions in this area?" and "What new tools, telescopes, observations, and calculations are needed to answer these questions?". All authors who have contributed to this book have devoted a significant part of their scientific careers to exploring the nature of neutron stars and understanding pulsars. Everyone has paid special attention to writing educational comprehensive review articles with the needs of beginners, students and young scientists as potential readers in mind. This book will be a valuable source of information for these groups.

Book Description
This volume is a collection of the Nobel Lectures delivered by the prizewinners, together with their biographies, portraits and the presentation speeches for the period 1991 ? 1995. Each Nobel Lecture is based on the work that won the prize. These volumes of inspiring lectures by outstanding physicists should be on the bookshelf of every keen student, teacher and professor of physics as well as of those in related fields.Below is a list of the prizewinners during the period 1991 ? 1995 with a description of the works which won them their prizes.(1991) P-G de GENNES?for discovering that methods developed for studying order phenomena in simple systems can be generalized to more complex forms of matter, in particular to liquid crystals and polymers; (1992) G CHARPAK ? for his invention and development of particle detectors, in particular the multiwire proportional chamber; (1993) R A HULSE & J-H TAYLOR JR. ? for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation; (1994) B N BROCKHOUSE ? for the development of neutron spectroscopy; C G SHULL ? for the development of the neutron diffraction technique; (1995) M L PERL ? for the discovery of the tau lepton; F REINES ? for the detection of the neutrino.

Book Description
Pulsar spindown forms a reliable yet enigmatic prototype for the energy loss processes in many astrophysical objects including accretion disks and back holes. In this paper we review the physics of pulsar magnetospheres, concentrating on recent developments in force-free modeling of the magnetospheric structure. In particular, we discuss a new method for solving the equations of time-dependent force-free relativistic MHD in application to pulsars. This method allows to dynamically study the formation of the magnetosphere and its response to perturbations, opening a qualitatively new window on pulsar phenomena. Applications of the method to other magnetized rotators, such as magnetars and accretion disks, are also discussed.

Book Description
The increasing power of computer resources along with great improvements in observational data in recent years have led to some remarkable and rapid advances in astrophysical fluid dynamics. The subject spans three distinct but overlapping communities whose interests focus on (1) accretion discs and high-energy astrophysics; (2) solar, stellar, and

Book Description
This book reports on the extraordinary observation of TeV gamma rays from the Crab Pulsar, the most energetic light ever detected from this type of object. It presents detailed information on the painstaking analysis of the unprecedentedly large dataset from the MAGIC telescopes, and comprehensively discusses the implications of pulsed TeV gamma rays for state-of-the-art pulsar emission models. Using these results, the book subsequently explores new testing methodologies for Lorentz Invariance Violation, in terms of a wavelength-dependent speed of light. The book also covers an updated search for Very-High-Energy (VHE), >100 GeV, emissions from millisecond pulsars using the Large Area Telescope on board the Fermi satellite, as well as a study on the promising Pulsar Wind Nebula candidate PSR J0631. The observation of VHE gamma rays is essential to studying the non-thermal sources of radiation in our Universe. Rotating neutron stars, also known as pulsars, are an extreme source class known to emit VHE gamma rays. However, to date only two pulsars have been detected with emissions above 100 GeV, and our understanding of their emission mechanism is still lacking.

Book Description
This monograph is based on my research work in pulsar astronomy, in which Chapters 3, 4, 6, 8, and 9 are mainly based on the previous works that need to be interpreted more deeply with the current progress in the relevant areas of the subjects. I hope this work will provide more insights about the state-switching of intermittent pulsars and the corresponding change in the pulsar magnetosphere. The link to the original paper is given under each chapter for convenience. I believe this monograph may have many defects and shortcomings. Any comments or suggestions are highly appreciated.

Book Description
It is usually assumed that the pulsar atmosphere consists of an open and a closed magnetosphere. There is, however, no generally accepted theory which predicts the boundary between these two regions. Contrary to expectation that the inertial effects would play the crucial role in determining this boundary, the author obtained the critical radius (R sub c) = (Omega R/C) sup( -2/5)R beyond which the lines of force are open, from the analysis of a corotational atmosphere, which is valid only in the absence of the inertial effects. The author also intends to clarify some of the processes underlying the theory of pair production and subsequent radio wave emission about a pulsar, as set forth by Sturrock. (Modified author abstract).
