Einstein established the theory of general relativity and the corresponding field equation in 1915 and its vacuum solutions were obtained by Schwarzschild and Kerr for, respectively, static and rotating black holes, in 1916 and 1963, respectively. They are, however, still playing an indispensable role, even after 100 years of their original discovery, to explain high energy astrophysical phenomena. Application of the solutions of Einstein's equation to resolve astrophysical phenomena has formed an important branch, namely relativistic astrophysics. I devote this article to enlightening some of the current astrophysical problems based on general relativity. However, there seem to be some issues with regard to explaining certain astrophysical phenomena based on Einstein's theory alone. I show that Einstein's theory and its modified form, both are necessary to explain modern astrophysical processes, in particular, those related to compact objects.Keywords

This book has been compiled based on the courses offered by the authors in Caltech and Stanford University, over a period of about four decades. Majority of the topics covered in the book are designed for a full-year course at the first-year Ph D (graduate) level (at least that is how the authors mostly used it when they taught). However, many final-year undergraduate (UG) students seem to be successful in grasping it as well. Many physics/astronomy/engineering students doing their research for Ph D use classical physics extensively.Full Text

The name Einstein has turned out to be almost like a dictionary word over various communities, scientific and otherwise. Being one of the great pillars of modern physics and generally science, Albert Einstein had been approached by academicians all over the world to resolve their scientific issues and/or otherwise. The Indian community was also in touch with Einstein on various occasions. The book under review deals with this topic.Full Text
