    Collapsing perfect fluid in self-similar five dimensional space-time and cosmic censorship
    (2011-07-06) Ghosh, S. G.; Sarwe, S. B.; Saraykar, R. V.
    We investigate the occurrence and nature of naked singularities in the gravitational collapse of a self-similar adiabatic perfect fluid in a five dimensional space-time. The naked singularities are found to be gravitationally strong in the sense of Tipler and thus violate the cosmic censorship conjecture.

    Non-adiabatic gravitational collapse of a superdense star
    (2010-06-01) Sarwe, S. B.; Tikekar, R.
    The relativistic equations governing the non-adiabatic shear-free collapse of massive superdense stars in the presence of dissipative forces producing heat flow in the background of space–times of the Vaidya–Tikekar ansatz with associated physical three-spaces that have the three-spheroidal geometry are formulated. It is shown how the system can be used to examine the development and progress of the collapse during subsequent epochs until the radiating star becomes a black hole.
