Astronomy has traditionally relied on capturing photons from cosmic sources to be able to understand the universe. During the 20th and 21st centuries, different messengers have been added to the astronomer's toolset: cosmic rays, neutrinos, and most recently gravitational waves. Each of these messengers opens a new window on the universe, and a modern astronomer must be familiar with them. The goal of this book is to provide a broad understanding of these messengers and their relationship to each other. The unique physics of each messenger is introduced, as well as the physics of their detection and interpretation. An additional focus is the discussion of techniques and topics that are common to more than one messenger. Principles of Multimessenger Astronomy is designed to be both an introduction and reference to modern astronomy.Key FeaturesProvides a general reference for all astronomers interested in multimessenger observational astronomy and astrophysics, as well as a teaching resourceExplores foundation topics that are useful across messenger and waveband boundariesIncludes scientific history, and the operation and use of modern astronomical instrumentationIntroduces the use of data from multiple messengers

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 FeaturesThe first book dedicated to the topicWritten by world-leading experts in the fieldProvides a thorough overview of theoretical foundations and state-of-art numerical modelsSuitable for graduate students and researchers

Understanding Stellar Evolution is based on a series of graduate-level courses taught at the University of Washington since 2004, and is written for physics and astronomy students and for anyone with a physics background who is interested in stars. It describes the structure and evolution of stars, with emphasis on the basic physical principles and the interplay between the different processes inside stars. Based on these principles, the evolution of low- and high-mass stars is explained from their formation to their death.The physical effects described include nuclear reactions, energy transport, chemical mixing, pulsation, mass loss, and rotation. A short description of the evolution of interacting binaries is also included. Modern state-of-the-art evolution models that follow from these basic principles are compared with observations, providing a test for the understanding of the processes that occur inside stars. Where physical processes are complex, intuitive explanations are given in addition to the proper mathematical derivations, and simple figures are used to explain the key effects. In addition to homework exercises for each chapter, the text contains a large number of questions that are meant to stimulate the understanding of the physical principles. An extensive set of accompanying lecture slides is available for teachers in both Keynote® and PowerPoint® formats.
