  • Anisotropic extension of Finch and Skea stellar model Astrophysics and Space Science 
    Sharma Ranjan; Das Shyam; Thirukkanesh, S. (Astrophysics and Space Science, 2017)
    In this paper, the spacetime geometry of Finch and Skea [Class. Quantum Grav., 6 (1989) 467] has been utilized to obtain closed-form solutions for a spherically symmetric anisotropic matter distribution. By examining its ...
  • Anisotropic static spheres with linear equation of state in isotropic coordinates 
    Govender, M; Thirukkanesh, S. (Astrophysics and Space Science, 2015)
    In this paper we present a general framework for generating exact solutions to the Einstein field equations for static, anisotropic fluid spheres in comoving, isotropic coordinates obeying a linear equation of state of the ...
  • Causal heat flow in Bianchi type-V Universe 
    Govender, M; Thirukkanesh, S. (International Journal of Modern Physics, 2014)
    In this paper we investigate the role of causal heat transport in a spatially homogeneous, locally-rotationally symmetric Bianchi type-V cosmological model. In particular, the causal temperature profile of the cosmological ...
  • Charged relativistic spheres with generalized potentials 
    Thirukkanesh, S.; Maharaj, S. D. (Mathematical Methods in the Applied Sciences, 2009)
    A new class of exact solutions of the Einstein-Maxwell system is found in closed form. This is achieved by choosing a generalised form for one of the gravitational potentials and a particular form for the electric field ...
  • Dissipative collapse in the presence of Λ 
    Govender, M; Thirukkanesh, S. (International Journal of Theoretical Physics, 2009)
    We present the general junction conditions for the smooth matching of a spherically symmetric, shear-free spacetime to Vaidya’s outgoing metric across a four-dimensional time-like hypersurface in the presence of a cosmological ...
  • The final outcome of dissipative collapse in the presence of Λ, PRAMANA 
    Thirukkanesh, S.; Moopanar, S.; Govender, M (journal of Physics, 2012)
    We investigate the role played by the cosmological constant during gravitational collapse of a radiating star with vanishing Weyl stresses in the interior. We highlight the role played by the cosmological constant during ...
  • General relativistic model for mixed fluid sphere with equation of state 
    Ragel, F. C.; Thirukkanesh, S. (The European Physical Journal, 2019)
    We generate a general frame work to solve the Einstein system with an equation of state that describe static spherically symmetric anisotropic matter distribution in terms of a generating function. It is examined for a Van ...
  • Mixed potentials in radiative stellar collapse 
    Thirukkanesh, S.; Maharaj, S. D. (Journal of Mathematical Physics, 2010)
    We study the behaviour of a radiating star when the interior expanding, shearing fluid particles are traveling in geodesic motion. We demonstrate that it is possible to obtain new classes of exact solutions in terms of ...
  • Radiating relativistic matter in geodesic motion 
    Thirukkanesh, S.; Maharaj, S. D. (Journal of Mathematical Physics, 2009)
    We study the gravitational behaviour of a spherically symmetric radiating star when the fluid particles are in geodesic motion. We transform the governing equation into a simpler form which allows for a general analytic ...
  • Shearing radiative collapse with expansion and acceleration 
    Thirukkanesh, S.; Rajah, S. S.; Maharaj, S. D. (Journal of Mathematical Physics, 2012)
    We investigate the behaviour of a relativistic spherically symmetric radiative star with an accelerating, expanding and shearing interior matter distribution in the presence of anisotropic pressures. The junction condition ...
  • Some new static charged spheres 
    Maharaj, S. D.; Thirukkanesh, S. (Nonlinear Analysis- Real World Applications, 2009)
    We present new exact solutions for the Einstein-Maxwell system in static spherically symmetric interior spacetimes. For a particular form of the gravitational potentials and the electric field intensity, it is possible ...
  • Spherically symmetric static matter configurations with vanishing radial pressure 
    Thirukkanesh, S.; Govender, M; Lortan, D. B (International Journal of Modern Physics, 2015)
    We present a new family of spherically symmetric, static solutions of the Einstein field equations in isotropic, comoving coordinates. The radial pressure at each interior point of these models vanishes yet equilibrium is ...
