A group theoretic approach to shear-free radiating stars
G. Abebe, S. D. Maharaj, K. S. Govinder
A systematic analysis of the junction condition, relating the radial pressure with the heat flow in a shear-free relativistic radiating star, is undertaken. This is a highly nonlin…
Generalized Euclidean stars with equation of state
G. Z. Abebe, S. D. Maharaj, K. S. Govinder
We consider the general case of an accelerating, expanding and shearing model of a radiating relativistic star using Lie symmetries. We obtain the Lie symmetry generators that leav…
Geodesic models generated by Lie symmetries
G. Z. Abebe, S. D. Maharaj, K. S. Govinder
We study the junction condition relating the pressure to the heat flux at the boundary of a shearing and expanding spherically symmetric radiating star when the fluid particles are…
Lie symmetries for a conformally flat radiating star
G. Abebe, K. S. Govinder, S. D. Maharaj
We consider a relativistic radiating spherical star in conformally flat spacetimes. In particular we study the junction condition relating the radial pressure to the heat flux at t…
