Book Description
It is over a quarter of a century since the discovery of out?ows from young stars. The intervening years have led to remarkable advances in our understanding of this phenomenon. Much of the progress can be attributed to advances in facilities and technologies, including not only larger telescopes but also improved instrument and detector performance. In addition protostellar out?ows have now been imaged from the ground and space at high spatial resolution, e. g. with HST, and at a wide - riety of wavelengths from X-rays to radio waves, revealing more and more about their physics. This veritable revolution in observation has been accompanied by an exponential growth in our ability to numerically simulate the launching and pro- gation of jets. Codes continue to improve: they now incorporate more physics and are increasingly ef?cient through, for example, techniques such as adaptive mesh re?nement and the use of parallel processing in cluster environments. Simulating the launching and propagation of a jet all the way from the vicinity of the star up to 4 several thousand AU (a size range of10 ) is now much closer. In more recent times, developments in observation, theory and numerical s- ulation have been joined by laboratory jet experiments reproducing, on centimetre scales, that which is seen in astrophysics to stretch for several parsecs.

Book Description
Radiative Processes in Astrophysics: This clear, straightforward, and fundamental introduction is designed to present-from a physicist's point of view-radiation processes and their applications to astrophysical phenomena and space science. It covers such topics as radiative transfer theory, relativistic covariance and kinematics, bremsstrahlung radiation, synchrotron radiation, Compton scattering, some plasma effects, and radiative transitions in atoms. Discussion begins with first principles, physically motivating and deriving all results rather than merely presenting finished formulae. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the field as well as the ideal text for senior or first-year graduate students of astronomy, astrophysics, and related physics courses. Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the material and methods for calculating results. This important and integral section emphasizes physical intuition by presenting important results that are used throughout the main text; it is here that most of the practical astrophysical applications become apparent.

Book Description
Since it was first published in 1987, Galactic Dynamics has become the most widely used advanced textbook on the structure and dynamics of galaxies and one of the most cited references in astrophysics. Now, in this extensively revised and updated edition, James Binney and Scott Tremaine describe the dramatic recent advances in this subject, making Galactic Dynamics the most authoritative introduction to galactic astrophysics available to advanced undergraduate students, graduate students, and researchers. Every part of the book has been thoroughly overhauled, and many sections have been completely rewritten. Many new topics are covered, including N-body simulation methods, black holes in stellar systems, linear stability and response theory, and galaxy formation in the cosmological context. Binney and Tremaine, two of the world's leading astrophysicists, use the tools of theoretical physics to describe how galaxies and other stellar systems work, succinctly and lucidly explaining theoretical principles and their applications to observational phenomena. They provide readers with an understanding of stellar dynamics at the level needed to reach the frontiers of the subject. This new edition of the classic text is the definitive introduction to the field. ? A complete revision and update of one of the most cited references in astrophysics Provides a comprehensive description of the dynamical structure and evolution of galaxies and other stellar systems Serves as both a graduate textbook and a resource for researchers Includes 20 color illustrations, 205 figures, and more than 200 problems Covers the gravitational N-body problem, hierarchical galaxy formation, galaxy mergers, dark matter, spiral structure, numerical simulations, orbits and chaos, equilibrium and stability of stellar systems, evolution of binary stars and star clusters, and much more Companion volume to Galactic Astronomy, the definitive book on the phenomenology of galaxies and star clusters

Book Description
In The Earth as a Distant Planet, the authors become external observers of our solar system from a distance and try to determine how one can understand how Earth, the third in distance to the central star, is essentially unique and capable of sustaining life. The knowledge gained from this original perspective is then applied to the search for other planets outside the solar system, or exoplanets. Since the discovery in 1992 of the first exoplanet, the number of planet detections has increased exponentially and ambitious missions are already being planned for the future. The exploration of Earth and the rest of the rocky planets are Rosetta stones in classifying and understanding the multiplicity of planetary systems that exist in our galaxy. In time, statistics on the formation and evolution of exoplanets will be available and will provide vital information for solving some of the unanswered questions about the formation, as well as evolution of our own world and solar system. Special attention is paid to the biosignatures (signs of life) detectable in the Earth's reflected spectra and the search for life in the universe. The authors are experts on the subject of extrasolar planets. They provide an introductory but also very much up-to-date text, making this book suitable for researchers and for advanced students in astronomy and astrophysics.

Book Description
The only thing we can be absolutely sure of is our own consciousness. But what is consciousness? Is it a property that is unique to humans or do we share it with other lifeforms? Or is the philosophical doctrine of panpsychism correct—are stars and the entire universe conscious in some sense? Early chapters in this book examine the prehistory, mythology, and history of this topic. Arguments are presented from the viewpoints of shamans, philosophers, poets, quantum physicists, and novelists. A simple “toy” model of panpsychism is then presented, in which a universal field of proto- consciousness interacts with molecular bonds via the vacuum fluctuation pressure of the Casimir Effect. It is shown how this model is in congruence with an anomaly in stellar motions called “Parenago’s Discontinuity.” Cool, redder, less massive stars such as the Sun apparently circle the center of the galaxy faster than their hotter, bluer, more massive sisters. This discontinuity occurs at the point in the stellar distribution where molecules begin to appear in stellar spectra. As described in the first edition of this book, observations of main sequence stars out to ~260 light years and giant stars out to >1,000 light years—using the ESA Hipparcos space observatory—support the reality and non-locality of Parenago’s Discontinuity. Local, more conventional explanations for this phenomenon are not supported by observations of other galaxies and the spiral arms of the Milky Way. Since 2014, the new ESA Gaia space observatory has been obtaining kinematics and position data for ~1 billion stars in our galaxy. The first Gaia data release in 2016 has been used in 2018 by a Russian team to demonstrate Parenago’s Discontinuity for a large stellar sample out to ~500 light years from the Sun. These observations support the hypothesis that anomalistic stellar motion is due to stellar volition, as described by philosopher/author Olaf Stapledon in his classic novel Star Maker, as previously discussed by the author in the peer-reviewed Journal of the British Interplanetary Society (JBIS). In light of the new Gaia observations and work by other researchers, it is not impossible that panpsychism is emerging from the realm of philosophy as a new subdivision of observational astronomy. Simple models of universal proto-consciousness may be subject to inductive tests using current and future space observatories. A special feature of this book is the chapter frontispiece art by C Bangs.
