    • Anisotropic stars in general relativity. 

      Chaisi, Mosa. (2004)
      In this thesis we seek new solutions to the anisotropic Einstein field equations which are important in the study of highly dense stellar structures. We first adopt the approach used by Maharaj & Maartens (1989) to obtain ...
    • Conformally invariant relativistic solutions. 

      Maharaj, M. S. (1993)
      The study of exact solutions to the Einstein and Einstein-Maxwell field equations, by imposing a symmetry requirement on the manifold, has been the subject of much recent research. In this thesis we consider specifically ...
    • Exact models for radiating relativistic stars. 

      Rajah, Suryakumari Surversperi. (2007)
      In this thesis, we seek exact solutions for the interior of a radiating relativistic star undergoing gravitational collapse. The spherically symmetric interior spacetime, when matched with the exterior radiating Vaidya ...
    • New analytical stellar models in general relativity. 

      Thirukkanesh, Suntharalingam. (2009)
      We present new exact solutions to the Einstein and Einstein-Maxwell field equations that model the interior of neutral, charged and radiating stars. Several new classes of solutions in static spherically symmetric interior ...
    • On the status of the geodesic law in general relativity. 

      Nevin, Jennifer Margaret. (1998)
      The geodesic law for test particles is one of the fundamental principles of general relativity and is extensively used. It is thought to be a consequence of the field laws but no rigorous proof exists. This thesis is ...
    • Realistic charged stellar models 

      Komathiraj, Kalikkuddy. (2007)
      In this thesis we seek exact solutions to the isotropic Einstien-Maxwell system that model the interior of relativistic stars. The field equations are transformed to a simpler form using the transformation of Durgapal and ...
    • Spherically symmetric cosmological solutions. 

      Govender, Jagathesan. (1996)
      This thesis examines the role of shear in inhomogeneous spherically symmetric spacetimes in the field of general relativity. The Einstein field equations are derived for a perfect fluid source in comoving coordinates. ...
    • Stellar structure and accretion in gravitating systems. 

      John, Anslyn James. (2012)
      In this thesis we study classes of static spherically symmetric solutions to the Einstein and Einstein–Maxwell equations that may be used to model the interior of compact stars. We also study the spherical accretion of ...
