This book was released on 2013-02-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Type Ia supernovae (SNe Ia) are bright, distinctive explosions that are effective tools to study the expansion history of the Universe. Given their importance, it is remarkable that we still do not know the exact nature or natures of the astrophysical systems that generate them. IAU Symposium 281 assesses the state of searches for the progenitor systems and describes progress toward the solution of the so-called Type Ia progenitor puzzle. This long-standing problem has proved difficult to solve, because it involves so many areas at the frontiers of astrophysics. Topics covered include: work on new surveys; studies of white dwarfs, accretion binaries, and related phenomena; binary evolution models and different ways to test them; and SNe Ia explosions, light curves and supernova remnants. This volume presents all sides of the ongoing debates, benefiting researchers and graduate students working on Type Ia supernovae, close binary evolution, and binary populations.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Type Ia supernovae are generally agreed to arise from thermonuclear explosions of carbon-oxygen white dwarfs, which are led to explode via interaction with a companion star in a binary system. The actual path to explosion, however, remains uncertain, with numerous plausible parent systems and explosion mechanisms suggested. Observationally, Type Ia supernovae have multiple subclasses, distinguished by their light curves and spectra. This raises the question of whether these differences reflect multiple mechanisms occurring in nature or, instead, that explosions can be described by variations of a few physical properties. In this thesis, I use a spectral modeling package to investigate whether the spectra of events of distinct subclasses can be understood as part of a spectral sequence, where one parameter is varied at a time. I find that a single ejecta structure is sufficient to provide reasonable fits for spectra that are prototypical of subluminous and normal events. These spectra can be obtained provided that the luminosity (and thus temperature) of the ejecta are adjusted appropriately. Using a similar method, I also study the distribution of unburned material in SN 2011fe, finding a relatively large range of solutions, which does not rule out the predictions of most physical models. Lastly, I investigate the time-dependent rate of supernovae resulting from a burst of star formation. This analysis can, in principle, discriminate among proposed evolutionary paths, because it is sensitive to the nature of the companion star. By modeling the rates as a power-law, I find a normalization constant that indicates that field and cluster galaxies may be explained by the same distribution, contrary to previous results. In addition, I also provide a state-of-the-art measurement of the slope of this distribution, finding that is intermediate between the various predictions and does not yet constrain the evolutionary path leading to Type Ia supernovae.

Download or read book Thermonuclear Supernovae written by P. Ruiz-Lapuente and published by Springer Science & Business Media. This book was released on 1997 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: All theoretical and observational topics relevant to the understanding of the thermonuclear (Type Ia) supernova phenomenon are thoroughly and consistently reviewed by a panel including the foremost experts in the field. The book covers all aspects, ranging from the observations of SNe Ia at all stages and all wavelengths to the 2D and 3D modelling of thermonuclear flames in very dense plasmas. Scenarios for close binary evolution leading to SNe Ia are discussed. Particular emphasis is placed on the homogeneity vs. diversity of SNe Ia and on their use as standard candles to measure cosmological parameters. The book reflects the recent and very significant progress made in both the modelling of the explosions and in the observational field.

Download or read book Nuclear Physics of Stars written by Christian Iliadis and published by John Wiley & Sons. This book was released on 2015-04-13 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Supernova Environmental Impacts IAU S296 written by Alak Ray and published by Cambridge University Press. This book was released on 2014-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: New telescopes spanning the full electromagnetic spectrum have enabled the study of supernovae (SNe) and supernova remnants (SNRs) to advance at a breathtaking pace. Automated synoptic surveys have increased the detection rate of supernovae by more than an order of magnitude and have led to the discovery of highly unusual supernovae. Observations of gamma-ray emission from SNRs with ground-based Cherenkov telescopes and the Fermi telescope have spawned new insights into particle acceleration in supernova shocks. Far-infrared observations from the Spitzer and Herschel observatories have told us much about the properties and fate of dust grains in SNe and SNRs. Work with satellite-borne Chandra and XMM-Newton telescopes and ground-based radio and optical telescopes reveal signatures of supernova interaction with their surrounding medium, their progenitor life history and of the ecosystems of their host galaxies. IAU Symposium 296 covers all these advances, focusing on the interactions of supernovae with their environments.
Download or read book The Physics of Fluids and Plasmas written by Arnab Rai Choudhuri and published by Cambridge University Press. This book was released on 1998-11-26 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: A good working knowledge of fluid mechanics and plasma physics is essential for the modern astrophysicist. This graduate textbook provides a clear, pedagogical introduction to these core subjects. Assuming an undergraduate background in physics, this book develops fluid mechanics and plasma physics from first principles. This book is unique because it presents neutral fluids and plasmas in a unified scheme, clearly indicating both their similarities and their differences. Also, both the macroscopic (continuum) and microscopic (particle) theories are developed, establishing the connections between them. Throughout, key examples from astrophysics are used, though no previous knowledge of astronomy is assumed. Exercises are included at the end of chapters to test the reader's understanding. This textbook is aimed primarily at astrophysics graduate students. It will also be of interest to advanced students in physics and applied mathematics seeking a unified view of fluid mechanics and plasma physics, encompassing both the microscopic and macroscopic theories.

Book excerpt: This book covers a very broad spectrum of experimental and theoretical activity in particle physics, from the searches for the Higgs boson and physics beyond the Standard Model, to detailed studies of Quantum Chromodynamics, the B-physics sectors and the properties of hadronic matter at high energy density as realised in heavy-ion collisions. Starting with a basic introduction to the Standard Model and its most likely extensions, the opening section of the book presents an overview of the theoretical and phenomenological framework of hadron collisions and current theoretical models of frontier physics. In part II, discussion of the theory is supplemented by chapters on the detector capabilities and search strategies, as well as an overview of the main detector components, the initial calibration procedures and physics samples and early LHC results. Part III completes the volume with a description of the physics behind Monte Carlo event generators and a broad introduction to the main statistical methods used in high energy physics. LHC Phenomenology covers all of these topics at a pedagogical level, with the aim of providing young particle physicists with the basic tools required for future work on the various LHC experiments. It will also serve as a useful reference text for those working in the field.

This book was released on 2013-11-29 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings from the 2012 Fourth International Meeting on Gravitation and Cosmology, focusing on accelerated cosmic expansion This volume provides both an update and a review of the state of alternative theories of gravity in connection with the accelerated expansion of the universe issue. Different theoretical proposals exist to explain the acceleration in the cosmic expansion, generating the dark energy issue and opening the possibility to theories of gravity alternative to general relativity. Related issues such as the dark matter problem are also surveyed in order to give the readers profound insight on the subject from different points of view. Comprised of short talks and plenary lectures given by leading experts in the field, some of them with brilliant and historic contributions, the book allows the reader to find readable and referenced surveys in topics like f(R) theories, the dark matter and dark energy issues, Modified Newtonian Dynamics (MOND) scenarios, f(T) theories, scalar-tensor theories derived from non-Riemannian geometries, emergent universes, the cosmological constant and other topics of current interest for younger and senior physicists and graduate students. These proceedings are from the Fourth International Meeting on Gravitation and Cosmology, held in Guadalajara, Jalisco, México, from 20 - 25 May, 2012, was sponsored by ICTP- Trieste, Italy and COECyTJAL-Universidad de Guadalajara, México. This event is a series of scientific meetings started in 2004 in Cuba, focusing on current and selected topics in the fields of gravitation and cosmology.
