Eta Carinae and the Supernova Impostors by Kris Davidson,Roberta M. Humphreys Pdf

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.

Luminous Stars in Nearby Galaxies by Roberta M. Humphreys Pdf

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.

Things That Are by Amy Leach Pdf

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

Pulsating Stars by Márcio Catelan,Horace A. Smith Pdf

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.

The Physics and Astrophysics of Neutron Stars by Luciano Rezzolla,Pierre Pizzochero,David Ian Jones,Nanda Rea,Isaac Vidaña Pdf

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).

Circumstellar Media in Late Stages of Stellar Evolution by Robin E. S. Clegg,I. R. Stevens,W. P. S. Meikle Pdf

In the last throes of their lives, how do low- and high-mass stars interact with their immediate surroundings? How does the circumstellar medium affect the shape of a nebula? How are supernovae effected by a dense medium? And what do we understand of how stellar winds interact with their environments? These and many other exciting issues are addressed in these proceedings, from the 34th Herstmonceux conference, held in Cambridge. Highlights of developments in the field covered in this volume include the latest observational results that show how various types of stellar ejecta differ in shape, and a unified view of the physical processes involved; as well as the latest results on the media around supernovae 1987A and 1993J. This timely volume provides review articles that serve both as an excellent introduction for graduate students, and a handy reference for researchers; and up-to-date research papers for those who want to keep abreast of developments in the field.

Supernovae and Nucleosynthesis by David Arnett Pdf

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.
