  • Anisotropic spheres with Van der Waals-type equation of state 
    Thirukkanesh, S.; Ragel, F. C. (INDIAN ACAD SCIENCES and SPRINGER, 2014)
    We study static spherically symmetric space-time to describe relativistic compact objects with anisotropic matter distribution and derive two classes of exact models to the Einstein–Maxwell system with a modified Van der ...
  • Strange star model with Tolmann IV type potential 
    Thirukkanesh, S.; Ragel, F. C. (Astrophysics and Space Science, 2014)
    We report a general solution in one of the gravitational potentials to the Einstein system in static spherically symmetric spacetime, modeling anisotropic strange quark matter by imposing a linear barotropic equation of ...
  • Anisotropic compact sphere with Van der Waals equation of state 
    Thirukkanesh, S.; Ragel, F. C. (Astrophysics and Space Science, 2014)
    We formulate a system of field equations with Van der Waals type equation of state to the Einstein field equations in spherically symmetric static spacetime to describe anisotropic compact matter and obtain a new class of ...
  • Hypergeometric Equation in Modeling Relativistic Isotropic Sphere 
    Thirukkanesh, S.; Ragel, F. C. (International Journal of Theoretical Physics, 2014)
    We study the Einstein system of equations in static spherically symmetric spacetimes. We obtained classes of exact solutions to the Einstein system by transforming the condition for pressure isotropy to a hypergeometric ...
  • Charged analogue of well behaved neutral spheres: an algorithmic approach 
    Thirukkanesh, S.; Ragel, F. C. (CHINESE PHYSICAL SOC, PEOPLES R CHINA and IOP Publishing Ltd, 2016)
    We establish a systematic algorithmic approach that generates new classes of solutions to the Einstein-Maxwell system in static spherically symmetric spacetime from well known uncharged solutions. A particular case is shown ...
  • A realistic model for charged strange quark star 
    Thirukkanesh, S.; Ragel, F. C. (CHINESE PHYSICAL SOC, PEOPLES R CHINA and IOP Publishing Ltd, 2017)
    e report a general approach to solve an Einstein-Maxwell system to describe a static spherically symmetric anisotropic strange matter distribution with linear equation of state in terms of two generating functions. It is ...
  • Anisotropic generalization of well-known solutions describing relativistic self-gravitating fluid systems: an algorithm 
    Thirukkanesh, S.; Ragel, F. C.; Sharma Ranjan; Das Shyam (The European Physical Journal, 2018)
    We present an algorithm to generalize a plethora of well-known solutions to Einstein field equations describing spherically symmetric relativistic fluid spheres by relaxing the pressure isotropy condition on the system. ...
