Book Description
In 1965 Fritz Zwicky proposed a class of supernovae that he called "Type V", described as "excessively faint at maximum". There were only two members, SN1961v and Eta Carinae. We now know that Eta Carinae was not a true supernova, but if it were observed today in a distant galaxy we would call it a "supernova impostor". 170 years ago it experienced a "great eruption" lasting 20 years, expelling 10 solar masses or more, and survived. Eta Carinae is now acknowledged as the most massive, most luminous star in our region of the Galaxy, and it may be our only example of a very massive star in a pre-supernova state. In this book the editors and contributing authors review its remarkable history, physical state of the star and its ejecta, and its continuing instability. Chapters also include its relation to other massive, unstable stars, the massive star progenitors of supernovae, and the "first" stars in the Universe.

Book Description
Studies on the populations of luminous stars in nearby resolved galaxies have revealed a complex distribution in the luminosity–temperature plane (the HR diagram). The fundamentals of massive star evolution are mostly understood, but the roles of mass loss, episodic mass loss, rotation, and binarity are still in question. Moreover, the final stages of these stars of different masses and their possible relation to each other are not understood. The purpose of this volume is to provide a current review of the different populations of evolved massive stars. The emphasis is on massive stars in the Local Group, the Magellanic Clouds, and the nearby spirals M31 and M33.

Book Description
Stars are mostly found in binary and multiple systems, with at least 50% of all solar-like stars having companions; this fraction approaches 100% for the most massive stars. A large proportion of these systems interact and alter the structure and evolution of their components, leading to exotic objects such as Algol variables, blue stragglers and other chemically peculiar stars, but also to phenomena such as non-spherical planetary nebulae, supernovae and gamma-ray bursts. While it is understood that binaries play a critical role in the Initial Mass Function, the interactions among binary systems significantly affect the dynamical evolution of stellar clusters and galaxies. This interdisciplinary volume presents results from state-of-the-art models and observations aimed at studying the impact of binaries on stellar evolution in resolved and unresolved populations. Serving as a bridge between observational and theoretical astronomy, it is a comprehensive review for researchers and advanced students of astrophysics.

Book Description
This book surveys our understanding of stars which change in brightness because they pulsate. Pulsating variable stars are keys to distance scales inside and beyond the Milky Way galaxy. They test our understanding not only of stellar pulsation theory but also of stellar structure and evolution theory. Moreover, pulsating stars are important probes of the formation and evolution of our own and neighboring galaxies. Our understanding of pulsating stars has greatly increased in recent years as large-scale surveys of pulsating stars in the Milky Way and other Local Group galaxies have provided a wealth of new observations and as space-based instruments have studied particular pulsating stars in unprecedented detail.

Book Description
This book summarizes the recent progress in the physics and astrophysics of neutron stars and, most importantly, it identifies and develops effective strategies to explore, both theoretically and observationally, the many remaining open questions in the field. Because of its significance in the solution of many fundamental questions in nuclear physics, astrophysics and gravitational physics, the study of neutron stars has seen enormous progress over the last years and has been very successful in improving our understanding in these fascinating compact objects. The book addresses a wide spectrum of readers, from students to senior researchers. Thirteen chapters written by internationally renowned experts offer a thorough overview of the various facets of this interdisciplinary science, from neutron star formation in supernovae, pulsars, equations of state super dense matter, gravitational wave emission, to alternative theories of gravity. The book was initiated by the European Cooperation in Science and Technology (COST) Action MP1304 “Exploring fundamental physics with compact stars” (NewCompStar).

Book Description
Essays by a Whiting Award winner: “Like a descendant of Lewis Carroll and Emily Dickinson . . . one of the most exciting and original writers in America.” —Yiyun Li, author of Must I Go Things That Are takes jellyfish, fainting goats, and imperturbable caterpillars as just a few of its many inspirations. In a series of essays that progress from the tiniest earth dwellers to the most far-flung celestial bodies—considering the similarity of gods to donkeys, the inexorability of love and vines, the relations of exploding stars to exploding sea cucumbers—Amy Leach rekindles a vital communion with the wild world, dormant for far too long. Things That Are is not specifically of the animal, the human, or the phenomenal; it is a book of wonder, one the reader cannot help but leave with their perceptions both expanded and confounded in delightful ways. This debut collection comes from a writer whose accolades precede her: a Whiting Award, a Rona Jaffe Award, a Best American Essays selection, and a Pushcart Prize, all received before her first book-length publication. Things That Are marks the debut of an entirely new brand of nonfiction writer, in a mode like that of Ander Monson, John D’Agata, and Eula Biss, but a new sort of beast entirely its own. “Explores fantastical and curious subjects pertaining to natural phenomena . . . for those interested in looking at the natural world through the lens of a fairy tale, this is a bonbon of a book.” —Kirkus Reviews

Book Description
Celebration of the scientific accomplishments of the Far Ultraviolet Spectroscopic Explorer mission and a look toward to the future of astronomical ultraviolet spectroscopy. FUSE expanded the far-ultraviolet discovery space by a factor of ~10,000 beyond previous space missions. The science drivers that will help define the next far-ultraviolet capability were discussed.
