Book Description
Neutron stars hold a central place in astrophysics, not only because they are made up of the most extreme states of the condensed matter, but also because they are, along with white dwarfs and black holes, one of the stable configurations that stars reach at the end of stellar evolution. Neutron stars posses the highest rotation rates and strongest magnetic fields among all stars. They radiate prolifically, in high energy electromagnetic radiation and in the radio band. This book is devoted to the selected lectures presented in the 6th NATO-ASI series entitled "The Electromagnetic Spectrum of Neutron Stars" in Marmaris, Turkey, on 7-18 June 2004. This ASI is devoted to the spectral properties of neutron stars. Spectral observations of neutron stars help us to understand the magnetospheric emission processes of isolated radio pulsars and the emission processes of accreting neutron stars. This volume includes spectral information from the neutron stars in broadest sense, namely neutrino and gravitational radiation along with the electromagnetic spectrum. We believe that this volume can serve as graduate level of text including the broad range of properties of neutron stars.

Book Description
"A first-principles discussion of the fundamental neutron interactions . . . the writing is clear, and the explanations stress essential physical principles . . . an excellent survey."—Physics Today "A must for libraries of all universities and laboratories that are engaged in nuclear physics, particle physics, nuclear energy, astrophysics or condensed matter research . . . an outstanding multidisciplinary introduction to the physics and applications of cold neutrons."—Physics World "So many tables, facts and figures . . . the coverage is remarkable."—American Scientist This encyclopedic reference work covers nearly every conceivable aspect of neutron physics. Assembled by an expert in the field, it ranges from the neutron's role as a major element in tests of the standard model of astro-particle physics to its use in nuclear energy generation and the study of condensed matter systems. The multidisciplinary approach includes detailed treatment of strong, weak, and electromagnetic properties of the neutron as well as parallel developments in cosmology and astrophysics. Each subject is placed within its scientific context and receives considerable attention to historical detail.

Book Description
The ideal text for a one-semester course in radio astronomy Essential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners. This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts—succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book's approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism. Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike. The only textbook specifically designed for a one-semester course in radio astronomy Starts from first principles Makes teaching easier for astronomy professors who are not expert radio astronomers Emphasizes the physical processes in radio sources Covers the principles behind radio telescopes and receivers Provides the essential equations and fundamental constants used by practitioners Supplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrations An online illustration package is available to professors

Book Description
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.

Book Description
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.
