  • The general solution for relativistic spherical shells 
    Kijowski, J.; Magli, G.; Malafarina, D. (2005)
    The general exact solution of the Einstein-matter field equations describing spherically symmetric shells satisfying an equation of state in closed form is discussed under general assumptions of physical reasonableness. ...
  • The instability of black hole formation in gravitational collapse 
    Joshi, Pankaj S.; Malafarina, D. (2011-01-11)
    We consider here the classic scenario given by Oppenheimer, Snyder, and Datt, for the gravitational collapse of a massive matter cloud, and examine its stability under the introduction of small tangential stresses. We show, ...
  • Thermodynamics and gravitational collapse 
    Malafarina, D.; Joshi, Pankaj S. (2011-06-19)
    It is known now that a typical gravitational collapse in general relativity, evolving from regular initial data and under physically reasonable conditions would end in either a black hole or a naked singularity final state. ...
  • 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 ...
