  • Charged anisotropic matter with a linear equation of state, Classical and Quantum Gravity 
    Thirukkanesh, S; Maharaj, S. D. (Classical and Quantum Gravity, 2008)
    We consider the general situation of a compact relativistic body with anisotropic pressures in the presence of the electromagnetic field. The equation of state for the matter distribution is linear and may be applied to ...
  • Exact models for isotropic matter 
    Thirukkanesh, S; Maharaj, S. D. (Classical and Quantum Gravity, 2006)
    We study the Einstein-Maxwell system of equations in spherically symmetric gravitational fields for static interior spacetimes. The condition for pressure isotropy is reduced to a recurrence equation with variable, ...
  • Generalized isothermal models with strange equation of state 
    Thirukkanesh, S; Maharaj, S. D. (PRAMANA- journal of Physics, 2008)
    We consider the linear equation of state for matter distributions that may be applied to strange stars with quark matter. In our general approach the compact relativistic body allows for anisotropic pressures in the ...
  • Generating potentials via difference equations, 
    Maharaj, S. D.; Thirukkanesh, S (Mathematical Methods in the Applied Sciences, 2006)
    The condition for pressure isotropy, for spherically symmetric gravitational fields with charged and uncharged matter, is reduced to a recurrence equation with variable, rational coefficients. This difference equation is ...
  • New Classes of Charged Spheroidal Models 
    Thirukkanesh, S (Journal of Astrophysics, 2013)
    New classes of exact solutions to the Einstein-Maxwell system is found in closed form by assuming that the hypersurface t =constant is spheroidal. This is achieved by choosing a particular form for the electric field ...
  • Radiating fluid sphere immersed in an anisotropic atmosphere 
    Naidu, N. F; Govender, M; Thirukkanesh, S; Maharaj, S. D (General Relativity and Gravitation, 2017)
    We model a radiating star undergoing dissipative gravitational collapse in the form of radial heat flux. The exterior of the collapsing star is described by the generalised Vaidya solution representing a mixture of null ...
  • The role of the electromagnetic field in dissipative collapse 
    Thirukkanesh, S; Govender, M (International Journal of Modern Physics, 2013)
    In this paper, we investigate the effect of charge on the collapse of a radiating, shearing sphere. The junction conditions required for the smooth matching of a general spherically symmetric spacetime (in the absence of ...
