Null Fluid Collapse in Rastall Theory of Gravity
A Vaidya spacetime is considered for gravitational collapse of a type II fluid in the context of the Rastall theory of gravity. For a linear equation of state for the fluid profiles, the conditions
Strange stars with MIT bag model in the Rastall theory of gravity
The aim of this paper is to study the charged anisotropic strange stars in the Rastall framework. Basic formulation of field equations in this framework is presented in the presence of charged
Study of gravastars in Rastall gravity
Gravastars have been considered as a feasible alternative to black holes in the past couple of decades. Stable models of gravastar have been studied in many of the alternative gravity theories
Models of anisotropic compact stars in the Rastall theory of gravity
In the present work, we have studied the anisotropic compact stars in the regime of Rastall theory using Karori and Barua (KB)$(\mathit{KB})$ type metric. For this investigation, we have considered
Models of quintessence compact stars in Rastall gravity consistent with observational data
This work is devoted to present a new solution of field equations in the Rastall paradigm for isotropic matter content with quintessence field specified by the parameter $$\omega _q$$ ω q with the

Thermodynamic Analysis of the Static Spherically Symmetric Field Equations in Rastall Theory
The restrictions on the Rastall theory due to application of the Newtonian limit to the theory are derived. In addition, we use the zero-zero component of the Rastall field equations as well as the
Traversable asymptotically flat wormholes in Rastall gravity
There are some gravitational theories in which the ordinary energy-momentum conservation law is not valid in the curved spacetime. Rastall gravity is one of the known theories in this regard which

Universality of isothermal fluid spheres in Lovelock gravity
We show universality of isothermal fluid spheres in pure Lovelock gravity where the equation of motion has only one $N$th order term coming from the corresponding Lovelock polynomial action of degree

To find more deliberate f(R,T) cosmological solutions, we proceed our previous paper further by studying some new aspects of the considered models via investigation of some new cosmological
Rotating black hole in Rastall theory
Rotating black hole solutions in theories of modified gravity are important as they offer an arena to test these theories through astrophysical observation. The non-rotating black hole can be hardly
