The observational evidence for black holes is reviewed, some recent developments involving cosmic censorship and the statistical origin of black hole entropy are described, and some of their properties are described.Expand

The physics of black holes is explored in terms of a membrane paradigm which treats the event horizon as a two-dimensional membrane embedded in three-dimensional space. A 3+1 formalism is used to… Expand

It is known that there can be no gravitational, electromagnetic, or scalar field perturbations (except angular momentum) of a Schwarzschild black hole. A gravitationally collapsing star with… Expand

Even-parity electromagnetic and gravitational linear perturbations of Oppenheimer-Snyder collapse are studied. The even-parity electromagnetic problem is shown to be identical to the analogous… Expand

Important and useful to every student of relativity, this book is a unique collection of some 475 problems--with solutions--in the fields of special and general relativity, gravitation, relativistic… Expand

It is plausible that an accretion disk pumps energy into an outer tenuous layer of its atmosphere to form a high-tmeperature corona analogous to the solar corona. General features of such a corona,… Expand
