PDF-(BOOS)-Theory of Stellar Atmospheres: An Introduction to Astrophysical Non-equilibrium

This book provides an indepth and selfcontained treatment of the latest advances achieved in quantitative spectroscopic analyses of the observable outer layers of stars and similar objects Written by two leading researchers in the field it presents a comprehensive account of both the physical foundations and numerical methods of such analyses The book is ideal for astronomers who want to acquire deeper insight into the physical foundations of the theory of stellar atmospheres or who want to learn about modern computational techniques for treating radiative transfer in nonequilibrium situations It can also serve as a rigorous yet accessible introduction to the discipline for graduate students br Provides a comprehensive uptodate account of the field br Covers computational methods as well as the underlying physics br Serves as an ideal reference book for researchers and a rigorous yet accessible textbook for graduate students br An online illustration package is available to professors at pressprincetonedu br .

ABSTRACT -- The . well-defined, massive disk of young stars orbiting within 0.5 pc of the Galactic black hole (GBH) is strongly tilted with respect to the Galactic plane. In the context of in situ formation mechanisms, this orientation is inherited from that of the gas disk that formed these stars on the order of 6 million years ago. The tilt can be understood by positing that clouds fall toward the GBH on near-zero angular momentum orbits and form dispersion rings as they self-intersect after . H.-W.
