Taschenbuch. Condizione: Neu. Neuware - Common envelope evolution is the most important phase in the lives of many significant classes of binary stars. During a common envelope phase, the stars temporarily share the same outer layers, with the cores of both stars orbiting inside the same common envelope. This common envelope is sometimes ejected and helps to explain the formation of a wide variety of astrophysical phenomena, including cataclysmic variables, X-ray binaries, progenitors for type Ia supernovae, and gravitational-wave mergers.Modeling common envelope evolution is a challenging problem, and this important process has typically been described in evolutionary models using very approximate treatments. This book explains the physics of common envelope evolution and relates it to the approximations that are frequently used for modeling the onset, progression, and outcome of common envelope phases.Key Features - The first book dedicated to the topic - Written by world-leading experts in the field - Provides a thorough overview of theoretical foundations and state-of-art numerical models - Suitable for graduate students and researchers.…

Buch. Condizione: Neu. Neuware - This book is different to other electronics texts available. First, it is short. Created for a one-semester course taken by physics students, both undergraduate and graduate it includes only the essentials and covers those topics only as deeply as needed in order to understand the material in the integrated laboratory exercises. Unlike many electronics texts for physics students, this one does not delve into the physics of devices. Instead, these are largely treated as black boxes having certain properties that are important to know for designing circuits. The physics comes when the students use their acquired electronics instrumentation knowledge to construct apparatus to make measurements. Since the detailed physics has been left out, this book should be equally useful for students in any of the physical or life sciences. This is the first textbook aimed at the non-electrical engineering student, that has both the generality on analog and digital electronics circuits, coupled to the very timely technology of embedded electronics. The book also features homework exercises, parts list and a suite of useful appendices.Key Features - Combined lectures and laboratory course - Covers analog and digital electronics - Includes embedded systems - Homework problems with solutions - Complete inventory of required components.…
