Lie Symmetry Analysis of the Einstein-Maxwell Equations for Quark Stars
Muhammad Al-Zafar Khan, Riven Narain
We derive the Lie point symmetries for the MIT Bag Model for quark stars in relativistic astrophysics. Four cases of reduction arise; three cases of specific values of the measure…
Conformal symmetries in generalised Vaidya spacetimes
Samson Ojako, Rituparno Goswami, Sunil D. Maharaj +1
In this paper we excavate, for the first time, the most general class of conformal Killing vectors, that lies in the two dimensional subspace described by the null and radial co-or…
Riccati equations for bounded radiating systems
S. D. Maharaj, A. K. Tiwari, R. Mohanlal +1
We systematically analyze the nonlinear partial differential equation that determines the behaviour of a bounded radiating spherical mass in general relativity. Four categories of…
Radiating stars with exponential Lie symmetries
R. Mohanlal, S. D. Maharaj, A. K. Tiwari +1
We analyze the general model of a radiating star in general relativity. A group analysis of the under determined, nonlinear partial differential equation governing the model's grav…
