Investigating strong gravitational lensing effects by suppermassive black holes with Horndeski gravity
Jitendra Kumar, Shafqat Ul Islam, Sushant G. Ghosh
We study gravitational lensing in strong-field limit by a static spherically symmetric black hole in quartic scalar field Horndeski gravity having additional hair parameter , ev…
A generalized buchdahl model for compact stars in f (R;T) gravity
J. Kumar, H. D. Singh, A. K. Prasad
In this paper, we study the stellar structure in terms of alternative theory of gravity specially by f (R;T) gravity theory. Here, we consider the function f (R;T) = R+2VT where R…
Behavior of anisotropic fluids with Chaplygin equation of state in Buchdahl spacetime
Amit Kumar Prasad, Jitendra Kumar, Abhijit Sarkar
In the present study we have proposed a new model of an anisotropic compact star which admits the Chaplygin equation of state. For this purpose, we consider Buchdahl ansatz. We obt…
Strong gravitational lensing by rotating Simpson--Visser black holes
Shafqat Ul Islam, Jitendra Kumar, Sushant G. Ghosh
We investigate strong field gravitational lensing by rotating Simpson-Visser black hole, which has an additional parameter (), apart from mass () and rotation…
Anisotropic relativistic fluid spheres with a linear equation of state
Amit Kumar Prasad, Jitendra Kumar
In this work, we present a class of relativistic and well-behaved solution to Einstein's field equations for anisotropic matter distribution. We perform our analysis by using the B…
Pulsar PSR B0943+10 as an isotropic Vaidya-Tikekar type compact star : A comprehensive study
Jitendra Kumar, Puja Bharti
In this paper, we have constructed a model for well behaved isotropic compact star in the presence of charged perfect fluid, by considering a static and spherically symmetric metri…
An isotropic compact stellar model in curvature coordinate system consistent with observational data
Jitendra Kumar, Puja Bharti
This paper investigates a spherically symmetric compact relativistic body with isotropic pressure profiles within the framework of general relativity. In order to solve the Einstei…
