This book was released on 2007-12-13 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life cycle is one of the most important questions in gravitation theory and relativistic astrophysics, and is the foundation of black hole physics. General relativity predicts that continual gravitational collapse gives rise to a space-time singularity. Quantum gravity may take over in such regimes to resolve the classical space-time singularity. This book investigates these issues, and shows how the visible ultra-dense regions arise naturally and generically as an outcome of dynamical gravitational collapse. It will be of interest to graduate students and academic researchers in gravitation physics, fundamental physics, astrophysics, and cosmology. It includes a detailed review of research into gravitational collapse, and several examples of collapse models are investigated in detail.

Book excerpt: Black holes are one of the most fascinating predictions of general relativity. They are the natural product of the complete gravitational collapse of matter and today we have a body of observational evidence supporting the existence of black holes in the Universe. However, general relativity predicts that at the center of black holes there are spacetime singularities, where predictability is lost and standard physics breaks down. It is widely believed that spacetime singularities are a symptom of the limitations of general relativity and must be solved within a theory of quantum gravity. Since we do not have yet any mature and reliable candidate for a quantum gravity theory, researchers have studied toy-models of singularity-free black holes and of singularity-free gravitational collapses in order to explore possible implications of the yet unknown theory of quantum gravity. This book reviews all main models of regular black holes and non-singular gravitational collapses proposed in the literature, and discuss the theoretical and observational implications of these scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: This book journeys into one of the most fascinating intellectual adventures of recent decades - understanding and exploring the final fate of massive collapsing stars in the universe. The issue is of great interest in fundamental physics and cosmology today, from both the perspective of gravitation theory and of modern astrophysical observations. This is a revolution in the making and may be intimately connected to our search for a unified understanding of the basic forces of nature, namely gravity that governs the cosmological universe, and the microscopic forces that include quantum phenomena. According to the general theory of relativity, a massive star that collapses catastrophically under its own gravity when it runs out of its internal nuclear fuel must give rise to a space-time singularity. Such singularities are regions in the universe where all physical quantities take their extreme values and become arbitrarily large. The singularities may be covered within a black hole, or visible to faraway observers in the universe. Thus, the final fate of a collapsing massive star is either a black hole or a visible naked singularity. We discuss here recent results and developments on the gravitational collapse of massive stars and possible observational implications when naked singularities happen in the universe. Large collapsing massive stars and the resulting space-time singularities may even provide a laboratory in the cosmos where one could test the unification possibilities of basic forces of nature.

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the gravitational collapse of massive objects to form black holes has a long and fascinating history. The purpose of this book is to present a study on naked singularities arising in different dimensional gravitational collapse and its implication to cosmic censorship hypothesis for the university students and researchers who are pursuing this line of research. This book provides the study of gravitational collapse of spherically symmetric and non-spherically symmetric space-times and examine whether it ends into a black hole or a naked singularity.

This book was released on 2012-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visibility of spacetime singularities formed in the gravitational collapse of a star has been one of the most disputed topics of modern astrophysics and cosmology for the past four decades. This provocative, topical book presents the scientific foundation for thinking that spacetime singularities formed in the collapse of a star might be visible. The book portrays methods for determining the nature of singularities arising in four and higher dimensional spacetimes. It is the most comprehensive book, which will be an essential reading for astrophysicists, cosmologists and all those interested in understanding the gravitational collapse of a star.

This book was released on 2012-04 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive book for the post graduates and researchers in theoretical astrophysics who want to study the space-time singularities arising in the gravitational collapse from a mathematician s point of view. The study has become significant from the perspective of cosmic censorship hypothesis. Four and higher-dimensional space-times are investigated for the possibility of cosmic censorship violation. Analysis of space-time singularities formed in the gravitational collapse of a star is one of the most important areas of mathematical research today. The book provides methods to determine the stability and strength of the singularities arising in various space-times.

Available in PDF, EPUB and Kindle. Book excerpt: The generality of the formalism is elucidated in the final chapters of the thesis by looking at the coupling of both electromagnetism and scalar fields in the collapse models. The coupling of electromagnetism to general relativity is given by the Einstein-Maxwell equations, and we are therefore describing relativistic plasma physics. We give a covariant formulation of these plasma equations in 3 + 1 form and discuss the analogues of these equations in standard Newtonian plasma physics. The reduction of these equations to the spherically symmetric case is given in detail along with a further reduction to both the charged Vaidya spacetime in non-null coordinates and the Reissner-Nordström spacetime. Again, all regions of this spacetime are expressed in a single coordinate system and an initial value formalism for a collapsing charged fluid is discussed analogously to the non-electromagnetic case. The final chapter discusses the advantage of this formalism in the context of the gravitational collapse of non-spherical spacetimes. The simplest non-spherical spacetimes which emits gravitational radiation are the vacuum Robinson-Trautman spacetimes. However, generalizations of these spacetimes to include matter are not known. This final chapter is for the most part qualitative, and concentrates on providing causality to outgoing Robinson-Trautman spacetimes. We make significant progress in understanding this problem by establishing the Einstein field equations in intial value form for non-spherical spacetimes which include matter sources.
