Stars are the main factories of element production in the universe through a suite of complex and intertwined physical processes. Such stellar alchemy is driven by multiple nuclear interactions that through eons have transformed the pristine, metal-poor ashes leftover by the Big Bang into a cosmos with 100 distinct chemical species. The products of stellar nucleosynthesis frequently get mixed inside stars by convective transport or through hydrodynamic instabilities, and a fraction of them is eventually ejected into the interstellar medium, thus polluting the cosmos with gas and dust. The study of the physics of the stars and their role as nucleosynthesis factories owes much to cross-fertilization of different, somehow disconnected fields, ranging from observational astronomy, computational astrophysics, and cosmochemistry to experimental and theoretical nuclear physics. Few books have simultaneously addressed the multidisciplinary nature of this field in an engaging way suitable for students and young scientists. Providing the required multidisciplinary background in a coherent way has been the driving force for Stellar Explosions: Hydrodynamics and Nucleosynthesis. Written by a specialist in stellar astrophysics, this book presents a rigorous but accessible treatment of the physics of stellar explosions from a multidisciplinary perspective at the crossroads of computational astrophysics, observational astronomy, cosmochemistry, and nuclear physics. Basic concepts from all these different fields are applied to the study of classical and recurrent novae, type I and II supernovae, X-ray bursts and superbursts, and stellar mergers. The book shows how a multidisciplinary approach has been instrumental in our understanding of nucleosynthesis in stars, particularly during explosive events.

As evidenced by five Nobel Prizes in physics, radio astronomy in its 80-year history has contributed greatly to our understanding of the universe. Yet for too long, there has been no suitable textbook on radio astronomy for undergraduate students. Fundamentals of Radio Astronomy: Observational Methods is the first undergraduate-level textbook exclusively devoted to radio astronomy telescopes and observation methods. This book, the first of two volumes, explains the instrumentation and techniques needed to make successful observations in radio astronomy. With examples interspersed throughout and problems at the end of each chapter, it prepares students to contribute to a radio astronomy research team. Requiring no prior knowledge of astronomy, the text begins with a review of pertinent astronomy basics. It then discusses radiation physics, the collection and detection of astronomical radio signals using radio telescopes, the functioning of various components of radio telescopes, and the processes involved in making successful radio observations. The book also provides a conceptual understanding of the fundamental principles of aperture synthesis and a more advanced undergraduate-level discussion of real-world interferometry observations. Web Resource A set of laboratory exercises is available for download on the book’s CRC Press web page. These labs use the Small Radio Telescope (SRT) and the Very Small Radio Telescope (VSRT) developed for educational use by MIT’s Haystack Observatory. The web page also includes a Java package that demonstrates the principles of Fourier transforms, which are needed for the analysis of interferometric data.

Modern cosmology has changed significantly over the years, from the discovery to the precision measurement era. The data now available provide a wealth of information, mostly consistent with a model where dark matter and dark energy are in a rough proportion of 3:7. The time is right for a fresh new textbook which captures the state-of-the art in cosmology. Written by one of the world's leading cosmologists, this brand new, thoroughly class-tested textbook provides graduate and undergraduate students with coverage of the very latest developments and experimental results in the field. Prof. Nicola Vittorio shows what is meant by precision cosmology, from both theoretical and observational perspectives. This book is divided into three main parts: Part I provides a pedagogical, but rigorous, general relativity-based discussion of cosmological models, showing the evidence for dark energy, the constraints from primordial nucleosynthesis and the need for inflation Part II introduces density fluctuations and their statistical description, discussing different theoretical scenarios, such as CDM, as well as observations Part III introduces the general relativity approach to structure formation and discusses the physics behind the CMB temperature and polarization pattern of the microwave sky Carefully adapted from the course taught by Prof. Vittorio at the University of Rome Tor Vergata, this book will be an ideal companion for advanced students undertaking a course in cosmology.

Supernovae and Nucleosynthesis

An Investigation of the History of Matter, from the Big Bang to the Present

This book investigates the question of how matter has evolved since its origin in the Big Bang, from the cosmological synthesis of hydrogen and helium to the generation of the complex set of nuclei that comprise our world and our selves. A central theme is the evolution of gravitationally contained thermonuclear reactors, otherwise known as stars. Our current understanding is presented systematically and quantitatively, by combining simple analytic models with new state-of-the-art computer simulations. The narrative begins with the clues (primarily the solar system abundance pattern), the constraining physics (primarily nuclear and particle physics), and the thermonuclear burning in the Big Bang itself. It continues with a step-by-step description of how stars evolve by nuclear reactions, a critical investigation of supernova explosion mechanisms and the formation of neutron stars and of black holes, and an analysis of how such explosions appear to astronomers (illustrated by comparison with recent observations). It concludes with a synthesis of these ideas for galactic evolution, with implications for nucleosynthesis in the first generation of stars and for the solar system abundance pattern. Emphasis is given to questions that remain open, and to active research areas that bridge the disciplines of astronomy, cosmochemistry, physics, and planetary and space science. Extensive references are given.

Nuclear Physics of Stars

Most elements are synthesized, or "cooked", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book. It presents nuclear structure and reactions, thermonuclear reaction rates, experimental nuclear methods, and nucleosynthesis in detail. These topics are discussed in a coherent way, enabling the reader to grasp their interconnections intuitively. The book serves both as a textbook for advanced undergraduate and graduate students, with worked examples and end-of-chapter excercises, but also as a reference book for use by researchers working in the field of nuclear astrophysics.

Find a hotter place! is the insightful story of the tortured path that led to our current understanding of how the elements in the Universe came to be. This is a story which began in Greek Antiquity, with the first musings on the nature of matter and the void, and continues today with ever more refined analyses involving virtually every aspect of 20th century physics, astronomy, cosmology and information technology. Identifying the source of stellar energy, probing the earliest instants of the Universe, and discovering of how and where each element was made are some of the outstanding success stories of the 20th century, but have received little attention beyond the specialized literature.The year 2007 marks the 50th anniversary of the publication of one of the key papers on stellar nucleosynthesis, universally referred to as the B2FH paper. This book is a timely survey of how a new discipline OCo nuclear astrophysics OCo was born, and how it has matured. Almost completely non-technical, the book remains scientifically rigorous, and thereby fills an important gap.Science is not a linear process, as the ill-named OC scientific methodOCO might suggest to the unwary. The author emphasizes the meanders, the dead ends and the obsessive dogmas which have guided researchers through the 20th century. He also makes it clear that our understanding of where the elements come from has come through discoveries in diverse, not necessarily related, disciplines."
