A whole decades research collated, organised and synthesised into one single book! Following a 60-page review of the seminal treatises of Misner, Thorne, Wheeler and Weinberg on general relativity, Glendenning goes on to explore the internal structure of compact stars, white dwarfs, neutron stars, hybrids, strange quark stars, both the counterparts of neutron stars as well as of dwarfs. This is a self-contained treatment and will be of interest to graduate students in physics and astrophysics as well as others entering the field.
The book gives an extended review of theoretical and observational aspects of neutron star physics. With masses comparable to that of the Sun and radii of about ten kilometres, neutron stars are the densest stars in the Universe. This book describes all layers of neutron stars, from the surface to the core, with the emphasis on their structure and equation of state. Theories of dense matter are reviewed, and used to construct neutron star models. Hypothetical strange quark stars and possible exotic phases in neutron star cores are also discussed. Also covered are the effects of strong magnetic fields in neutron star envelopes.
Neutron stars represent natural laboratories where all kinds of processes and reactions take place in unusual and extremely dense matter. Neutron stars, being the compact objects of close attention for physicists and astronomers, are the sources of strictly periodic pulsed radiation. Every neutron star has its own unique characteristics of pulse frequency, radiation spectrum and intensity, but there are also the glitches and pauses that occur suddenly. All of this together raises many questions. For instance, what is the physics concerning these phenomena in general, and what changes can emerge in the properties of matter under extreme conditions specific to neutron stars? Investigation of some of these issues is one of the aims of this book, which is dedicated to the physics of neutron stars, in particular the influence of external fields and rotation on the properties of neutron stars, and reactions and transition of matter in its envelopes and depth. In this regard, the authors review the models of neutron stars involving not only local charge neutrality cases, but also the most recent models fulfilling global charge neutrality. The weak interactions are taken into account by requiring the β stability of the system. The strong interactions, processes and reactions are described on the basis of the methods of few-body and cluster physics in a wide range of densities. Both electromagnetic and gravitational interactions are accounted for when constructing the equation of the neutron star matter and the equilibrium structure of the system. The Einstein field equations are solved for static and rotating neutron stars equilibrium configurations. Basic parameters of neutron stars such as mass-radius relations, mass-central density relation and so on are calculated by fulfilling stability criteria required for stable neutron star configurations. The relativistic quadrupole moment takes into account the deviations due to rotation and deformation. In this respect, the class of axisymmetric static and stationary quadrupolar metrics, which satisfy Einsteins equations in empty space and in the presence of matter represented by a perfect fluid, is considered. The physical conditions that must be satisfied for a particular spacetime metric to describe the gravitational field of compact stars are formulated. It is also important to develop powerful tools for investigating the processes in nuclear cluster studies in association with stellar environment, including neutron stars. These tools are different variants of microscopic cluster models, which allow one to study and to predict the dynamics of numerous processes and nuclear reactions taking place at various objects in our Universe. The effects of density oscillation in some layers of neutron star envelopes are investigated in the frame of Faddeev equations in the case of neutron resonances that appear in crystalline nuclei structures. The authors formulate new experiments of thermal neutron scattering on piezo crystalline targets to imitate oscillation effects in neutron star envelopes. The main purpose of this book is to investigate processes, phenomena and reactions in neutron star physics with fundamental interactions described in a self-consistent manner to highlight some interesting effects using few-body and other analytical/numerical methods.
In seven lectures of a pedagogical nature aimed at both researchers and graduate students the authors review important aspects of hadronic physics. The book contains a comprehensive review of recent experimental results obtained at the GSI collider. In particular, it covers chiral symmetry at finite temperature and statistical methods applied to relativistic heavy ion collisions and gives a detailed presentation of the astrophysics of strange quark matter.
Ladies and Gentlemen, dear colleagues, Welcome in Bodrum to the NASion Hot and Dense Nuclear Matter! Welcome also to Mrs. Governor Dr. Lale AYTAMAN. We are very honored, that you, Governor of the Mugla-State, came here to greet us. We are particularly grateful to you that you offered help and assured us to do everything that we can enjoy two safe weeks in Bodrum, in this wonderful area of your country. I have chosen Bodrum as the place for our NASI because I like this historic region where many cultures meet (e. g. , Oriental and European (Greek, Roman) culture) and where you find numerous places which played a role in ancient science and in early Christianity- I mention Milet (Thales) and Ephesus (Apostle Paulus), both of which are close by. Our NASI will exhibit the most recent developments in high energy heavy ion physics. The meeting is both a school and a conference: A school, because there are very many advanced students, who frequently are themselves already top researchers, attending the lectures of distinguished scientists and leading researchers. It is also a conference because new material, new results of this exciting and wonderful field - our field - high energy heavy ion physics will be presented. It is the topic of hot and dense nuclear matter, which we are focusing on.
Feynman’s bestselling introduction to the mind-blowing physics of QED—presented with humor, not mathematics Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the public. In this extraordinary book, Feynman provides a lively and accessible introduction to QED, or quantum electrodynamics, an area of quantum field theory that describes the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned Feynman diagrams instead of advanced mathematics, Feynman clearly and humorously communicates the substance and spirit of QED to the nonscientist. With an incisive introduction by A. Zee that places Feynman’s contribution to QED in historical context and highlights Feynman’s uniquely appealing and illuminating style, this Princeton Science Library edition of QED makes Feynman’s legendary talks on quantum electrodynamics available to a new generation of readers.
Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.
Pulsars, generally accepted to be rotating neutron stars, are dense, neutron-packed remnants of massive stars that blew apart in supernova explosions. They are typically about 10 kilometers across and spin rapidly, often making several hundred rotations per second. Depending on star mass, gravity compresses the matter in the cores of pulsars up to more than ten times the density of ordinary atomic nuclei, thus providing a high-pressure environment in which numerous particle processes, from hyperon population to quark deconfinement to the formation of Boson condensates, may compete with each other. There are theoretical suggestions of even more ""exotic"" processes inside pulsars, such as the formation of absolutely stable strange quark matter, a configuration of matter even more stable than the most stable atomic nucleus, ^T56Fe. In the latter event, pulsars would be largely composed of pure quark matter, eventually enveloped in nuclear crust matter. These features combined with the tremendous recent progress in observational radio and x-ray astronomy make pulsars nearly ideal probes for a wide range of physical studies, complementing the quest of the behavior of superdense matter in terrestrial collider experiments. Written by an eminent author, Pulsars as Astrophysical Laboratories for Nuclear and Particle Physics gives a reliable account of the present status of such research, which naturally is to be performed at the interface between nuclear physics, particle physics, and Einstein's theory of relativity.
The masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray observations of accreting binaries and to gravitational wave observations of neutron stars formed during the coalescence of double neutron-star systems. This volume includes more than forty years of research to provide graduate students and researchers in astrophysics, gravitational physics and astronomy with the first self-contained treatment of the structure, stability and oscillations of rotating neutron stars. This monograph treats the equations of stellar equilibrium; key approximations, including slow rotation and perturbations of spherical and rotating stars; stability theory and its applications, from convective stability to the r-mode instability; and numerical methods for computing equilibrium configurations and the nonlinear evolution of their oscillations. The presentation of fundamental equations, results and applications is accessible to readers who do not need the detailed derivations.
Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.
