Book Description
Cool evolved stars are among the brightest point sources in the infrared sky, and contribute significantly to the interstellar dust of galaxies. They are in a short-lived but important stage of stellar evolution, characterized by pulsations, dust formation, and the production of expanding circumstellar shells. This conference highlighted the physics of evolved cool stars in relation to their stage of evolution, atmospheric structure and dynamics, stellar winds, and associated dust formation. The conference was held at the Millennium Centre near the campus of East Tennessee State University in Johnson City, Tennessee, in July 2007. It brought together astronomers, both professional and amateur, who are working on different aspects of cool star research. These included dust theorists, numerical modelers, and experts in observations at different wavelengths. The result of the meeting was a more complete picture of these stars, which is summarized in this volume. Several recent developments motivated the need for this conference. Current hydrodynamic models of evolved stars are now able to reproduce the optical/UV spectra of such stars. However, simultaneous modeling of the infrared spectrum has proven difficult. Also, adding dust to such modeling is problematic because of the complicated physics of dust formation, destruction, and emission in these dynamic environments. Furthermore, the exact evolutionary relationship between the various types of cool evolved stars still is uncertain. The perceptive reader will discover a number of provocative research directions embedded in the many fine contributions herein.

Book Description
The underlying astrophysical mechanisms of the objects known as asymptotic giant branch stars - the structures that occur during the dramatic period prior to a star's death - is the main theme of this text. Over the past three decades, asymptotic giant branch stars have become a topic of their own, and the contributions to this volume all focus on these entities themselves, rather than their connections to other fields of astronomy. Among the many topics covered are new methods of high- quality infrared observation and the more detailed and realistic simulations made possible by increasingly fast computers. This collection should be useful to graduate students who work in the field, teachers who want to address the subject in their courses, and to astronomers from various backgrounds who are interested in the astrophysics of AGB stars.

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
Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. - Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life - Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA - Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres
