  • Gravitational Collapse of Inhomogenous Perfect Fluid 
    Satin, Seema; Malafarina, D.; Joshi, Pankaj S. (2014)
    We study the complete gravitational collapse of a class of inhomogeneous perfect fluid models obtained by introducing small radial perturbations in an otherwise homogeneous matter cloud. The key feature that we assume for ...
  • Naked Singularities as Particle Accelerators II 
    Patil, Mandar; Joshi, Pankaj S.; Malafarina, D. (2011-02-14)
    We generalize here our earlier results on particle acceleration by naked singularities. We showed recently [1] that the naked singularities that form due to gravitational collapse of massive stars provide a suitable ...
  • Recent developments in gravitational collapse and spacetime singularities 
    Joshi, Pankaj S.; Malafarina, D. (2012-01-19)
    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 singularity under a wide variety of ...
  • Scalar field collapse and cosmic censorship 
    Goswami, Rituparno; Joshi, Pankaj S.; Malafarina, D. (2012-02-28)
    We analyze here the final fate of complete gravitational collapse of a massless scalar field within general relativity. A class of dynamical solutions with initial data close to the Friedmann-Lemaˆıtre-Robertson-Walker ...
  • Thermodynamics and the naked singularity in the Gamma-metric 
    Lochan, K.; Malafarina, D.; Singh, T.P. (2010-09-23)
    We investigate a possible way of establishing a parallel between the third law of black hole mechanics, and the strong version of the third law of thermodynamics. We calculate the surface gravity and area for a naked ...
