Exact EGB models for spherical static perfect fluids

- S. Hansraj, Brian Chilambwe, S. Maharaj
- Physics, Mathematics
- 8 February 2015

We obtain a new exact solution to the field equations for a 5-dimensional spherically symmetric static distribution in the Einstein–Gauss–Bonnet modified theory of gravity. By using a transformation,… Expand

Compact objects in pure Lovelock theory

- N. Dadhich, S. Hansraj, Brian Chilambwe
- Mathematics
- 24 July 2016

For static fluid interiors of compact objects in pure Lovelock gravity (involving ony one $N$th order term in the equation) we establish similarity in solutions for the critical odd and even $d=2N+1,… Expand

Universality of isothermal fluid spheres in Lovelock gravity

- N. Dadhich, S. Hansraj, S. Maharaj
- Geology
- 26 October 2015

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… Expand

New models for perfect fluids in EGB gravity

- Brian Chilambwe, S. Hansraj, S. Maharaj
- Physics, Mathematics
- 27 May 2015

We obtain new exact solutions to the field equations in the Einstein–Gauss–Bonnet (EGB) modified theory of gravity for a five-dimensional spherically symmetric static matter distribution. By using a… Expand

Role of pressure anisotropy on relativistic compact stars

- S. K. Maurya, A. Banerjee, S. Hansraj
- Physics
- 28 October 2017

We investigate a compact spherically symmetric relativistic body with anisotropic particle pressure profiles. The distribution possesses characteristics relevant to modeling compact stars within the… Expand

Deflection of light by black holes and massless wormholes in massive gravity

- K. Jusufi, Nayan Sarkar, F. Rahaman, A. Banerjee, S. Hansraj
- Physics
- 29 December 2017

Weak gravitational lensing by black holes and wormholes in the context of massive gravity (Bebronne and Tinyakov, JHEP 0904:100, 2009) theory is studied. The particular solution examined is… Expand

Stellar modelling of isotropic Einstein–Maxwell perfect fluid spheres of embedding class one

- S. Hansraj, Lushen Moodly
- Physics
- 1 June 2020

It is indeed remarkable that while charged anisotropic models with the embedding class one property are abundant, there are no reports of the physically important isotropic case despite its… Expand

Shadow images of Kerr-like wormholes

- Muhammed Amir, K. Jusufi, A. Banerjee, S. Hansraj
- PhysicsClassical and Quantum Gravity
- 20 June 2018

The study of shadow continues to be a major source of insight into compact astrophysical objects. Depending on the nature of compact objects and due to the strong gravitational lensing effect that… Expand

Generalized spheroidal spacetimes in 5-D Einstein–Maxwell–Gauss–Bonnet gravity

- S. Hansraj
- Physics
- 4 October 2016

The field equations for static EGBM gravity are obtained and transformed to an equivalent form through a coordinate redefinition. A form for one of the metric potentials that generalizes the… Expand
