Equilibrium stellar configurations in Rastall theory and linear equation of state
Sudan Hansraj, Ayan Banerjee
Amongst a number of modified theories of gravity, the Rastall theory has been propounded to address some shortcomings of the standard theory of general relativity. Our purpose is t…
Spherically symmetric isothermal fluids in gravity
Sudan Hansraj
We analyze the isothermal property in static fluid spheres within the framework of the modified theory of gravitation. The equation of pressure isotropy of the standard E…
Qualitative analysis of the Tolman metrics within the unimodular framework
Sudan Hansraj, Njabulo Mkhize
We investigate the behaviour of the Tolman metrics within the formalism of the trace-free (or unimodular) gravity. While this approach is similar to the standard Einstein field equ…
Shadow images of Kerr-like wormholes
Muhammed Amir, Kimet Jusufi, Ayan Banerjee +1
Investigations of shadows of astrophysical entities constitute a major source of insight into the evolution of compact objects. Such effects depend on the nature of the compact obj…
Impact of the Rastall parameter on perfect fluid spheres
Sudan Hansraj, Ayan Banerjee, Phongpichit Channuie
We examine the effects of the Rastall parameter on the behaviour of spherically symmetric static distributions of perfect fluid matter. It was claimed by Visser [Physics Letters B,…
