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 consider general relativistic homogeneous gravitational collapses for dust and radiation.
We show that replacing the density profile with an effective density justified by some …

We develop here a new procedure within Einstein's theory of gravity to generate equilibrium
configurations that result as the final state of gravitational collapse from regular initial …

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 investigate here the locally naked singularity formed due to a spherically symmetric
inhomogeneous collapsing cloud having nonzero isotropic pressure, in terms of its strength …

Nous montrons qu'il est possible d'obtenir, au moins certaines régions à l'intérieur de
configurations de matière statique sphériquement symétriques, de fluides anisotropes …

In the present paper, we study the thermal properties of the geometrically thin accretion
disks surrounding the null naked singularity (NNS) and the first type of Joshi-Malafarina …

We investigate here the local versus global visibility of a spacetime singularity formed due to
the gravitational collapse of a spherically symmetric dust cloud having a nonzero velocity …

In this paper, we investigate the properties of the Lense–Thirring precession frequency and
periastron precession of the relativistic bound orbits in slowly rotating naked singularity …
