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 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.
