On the Limitations of Karmarkar's Condition in Static, Conformally Flat Spacetimes
Samstuti Chanda, Ranjan Sharma, Sunil D. Maharaj
For a static and spherically symmetric spacetime, we investigate the class of exact solutions that arise when two fundamental geometric constraints are imposed simultaneously: the…
Physical properties and the maximum compactness bound of a class of compact stars in gravity
Arpita Ghosh, Abhishek Paul, Ranjan Sharma +1
Motivation: Motivated by the growing interest in understanding the role of non-metricity in describing dense stellar systems, in this paper, we study compact stellar configurations…
Electromagnetic extension of Buchdahl bound in gravity
Soumik Bhattacharya, Ranjan Sharma, Sunil D. Maharaj
We develop a static charged stellar model in gravity where the modification is assumed to be linear in which is the trace of the energy momentum tensor. The exterior s…
The role of pressure anisotropy on the maximum mass of cold compact stars
S. Karmakar, S. Mukherjee, R. Sharma +1
We study the physical features of a class of exact solutions for cold compact anisotropic stars. The effect of pressure anisotropy on the maximum mass and surface redshift is analy…
A class of relativistic stars with a linear equation of state
R. Sharma, S. D. Maharaj
By assuming a particular mass function we find new exact solutions to the Einstein field equations with an anisotropic matter distribution. The solutions are shown to be relevant f…
Radiating spherical collapse with heat flow
M. Govender
We present here a simple model of radiative gravitational collapse with radial heat flux which describes qualitatively the stages close to the formation of a superdense cold star.…
