A rotating three component perfect fluid source and its junction with empty space-time
R. J. Wiltshire
The Kerr solution for empty space-time is presented in an ellipsoidally symmetric coordinate system and it is used to produce generalised ellipsoidal metrics appropriate for the ge…
Relativistic fluid spheres with particular application in cosmology and gravitational collapse
Ron Wiltshire
A spherically symmetric comoving fluid solution of Einstein's equations is adapted for cosmological application by extending the geometry of standard FRW cosmology using a generali…
Isotropy, shear, symmetry and exact solutions for relativistic fluid spheres
Ron Wiltshire
The symmetry method is used to derive solutions of Einstein's equations for fluid spheres using an isotropic metric and a velocity four vector that is non-comoving. Initially the L…
Slowly rotating, compact fluid sources embedded in Kerr empty space-time
Ron Wiltshire
Spherically symmetric static fluid sources are endowed with rotation and embedded in Kerr empty space-time up to an including quadratic terms in an angular velocity parameter using…
Robertson-Walker fluid sources endowed with rotation characterised by quadratic terms in angular velocity parameter
R J Wiltshire
Einstein's equations for a Robertson-Walker fluid source endowed with rotation Einstein's equations for a Robertson-Walker fluid source endowed with rotation are presented upto and…
Slowly, rotating non-stationary, fluid solutions of Einstein's equations and their match to Kerr empty space-time
R. J. Wiltshire
A general class of solutions of Einstein's equation for a slowly rotating fluid source, with supporting internal pressure, is matched using Lichnerowicz junction conditions, to the…
