Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

It is now known that when a massive star collapses under the force of its own gravity, the
final fate of such a continual gravitational collapse will be either a black hole or a naked …

We investigate the key physical features that cause the development of a naked singularity,
rather than a black hole, as the end state of spherical gravitational collapse. We show that …

Abstract This Living Review updates a previous version [25] which is itself an update of a
review article [31]. Numerical exploration of the properties of singularities could, in principle …

An outstanding problem in gravitation theory and relativistic astrophysics today is to
understand the final outcome of an endless gravitational collapse. Such a continual collapse …

Gravitational collapse is one of the most fruitful subjects in gravitational physics. It is well
known that singularity formation is inevitable in complete gravitational collapse. It was …

We study the spherical collapse of a perfect fluid with an equation of state P= k ρ by full
general relativistic numerical simulations. For 0< k≲ 0. 0 3 6, it has been known that there …

We present a novel derivation of the Teukolsky-Starobinsky identities, based on properties
of the confluent Heun functions. These functions define analytically all exact solutions to the …

Abstract LeMaître-Tolman-Bondi models of spherical dust collapse have been used and
continue to be used extensively to study various stellar collapse scenarios. It is by now well …

Spherically symmetric inhomogeneous dust collapse has been studied in higher
dimensional space–time and the factors responsible for the appearance of a naked …
