Gravitational Collapse of an Inhomogeneous Fluid in Rastall Theory
Akbar Jahan, Naser Sadeghnezhad, Amir Hadi Ziaie
We study spherically symmetric gravitational collapse of an inhomogeneous fluid with anisotropic energy momentum tensor (EMT) in Rastall gravity. Considering a linear equation of s…

Novel Brans-Dicke Wormhole Solutions in Non-Vacuum Spacetimes
Amir Hadi Ziaie, Naser Sadeghnezhad, Akbar Jahan
In the present study we search for a new class of wormhole solutions in the framework of Brans-Dicke (BD) theory in the presence of anisotropic matter distribution. Considering a l…

Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity
Akbar Jahan, Halime Miraghaei, Shayesteh Ghaffari +1
Various types of inhomogeneous collapse models in general relativity (GR) lead to the formation of spacetime singularities either visible or hidden by a spacetime horizon. Our aim…
