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.

This book presents scientific research on the central theme of new states of matter and new phenomena in the universe. The topics covered range from the big bang, through topics including the formation of exotic stars, black holes and the plasma of quarks and gluons by heavy ion reactions, to the influence of dark matter and dark energy in the evolution of the universe. Scientific interest in these themes has been growing: together with the development of major projects such as AUGER, LHC, FERMI Telescope, FAIR/GSI and GEO/LIGO, the diversity and scope of research on such themes has been on the rise. The content is detailed enough to capture the interest of experts in the field and is useful for future explorations on these fascinating themes.

The Fourth International Workshop on New Worlds in Astroparticle Physics was the latest in the biennial series, held in Faro, Portugal. The program included both invited and contributed talks. Each of the sessions opened with a pedagogical overview of the current state of the respective field. The following topics were covered: cosmological parameters; neutrino physics and astrophysics; gravitational waves; beyond standard models: strings; cosmic rays: origin, propagation and interaction; matter under extreme conditions; supernovae and dark matter.The proceedings have been selected for coverage in: ?

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.

The Eighth Mexican School of Particles and Fields was organized by the Particles and Fields Division of the Mexican Physical Society. It brought together worldwide experts to give a series of courses and plenary lectures on particle physics (experiments and phenomenology), quantum field theory, string theory, and astroparticle physics. In addition to the lectures, research seminars were held providing a forum for participants to discuss their work. This book provides a summary of the recent advances in these fields.

This volume contains the proceedings of the IX International Conference on Hypernuclear and Strange Particle Physics (HYP 2006). This conference series is devoted to the progress of our knowledge about strangeness flavor in hadron and nuclear physics. Besides the traditional topics such as hadron structure, hypernuclear spectroscopy and weak decay of hypernuclei, a particular focus of this conference was on the properties of strange mesons and their binding in nuclear systems.

Pulsars as Physics Laboratories

The discovery 25 years ago of the remarkable objects which came to be known as pulsars, and their identification as neutron stars, fulfilled a prediction made more than 30 years earlier. Over 550 pulsars are now known, almost all detected at radio frequencies. Their pulse periods range from 1.5 ms to several seconds. Most pulsars are single neutron stars but, in an important subset, the pulsar is in a binary orbit with a companion star. Observations have revealed a wealth of detail about the structure and evolution of pulsars and the pulse-emission process, giving new insight into the behaviour of matter in the presence of extreme gravitational and electromagnetic fields. Pulsars have unique physical properties which make them nearly ideal as probes for a wide range of physical studies.

This book is an introduction to “multi-messenger” astrophysics. It covers the many different aspects connecting particle physics with astrophysics and cosmology and introduces astrophysics using numerous experimental findings recently obtained through the study of high-energy particles. Taking a systematic approach, it comprehensively presents experimental aspects from the most advanced laboratories and detectors, as well as the theoretical background. The book is aimed at graduate students and post-graduate researchers with a basic understanding of particle and nuclear physics. It will also be of interest to particle physicists working in accelerator/collider physics who are keen to understand the mechanisms of the largest accelerators in the Universe. The book draws on the extensive lecturing experience of Professor Maurizio Spurio from the University of Bologna.

The first extended work of its kind, Stars as Laboratories for Fundamental Physics stands at the intersection of two burgeoning fields, astrophysics and particle physics. Georg Raffelt, one of the world's leading researchers in this field, describes what the study of stars reveals about fundamental particle interactions. Raffelt presents the many uses of stellar astrophysics for research in basic particle physics. He focuses primarily on the properties and nongravitational interactions of elementary particles. Numerous graphs and figures complement the text. Stars as Laboratories for Fundamental Physics is a valuable reference for cosmologists, astrophysicists, and particle physicists.
