Absence of curvature singularities in symmetric perfect fluid spacetimes in Einstein-Gauss-Bonnet Gravity
Aavishkar Madhunlall, Chevarra Hansraj, Rituparno Goswami +1
In this paper we study the higher dimensional homogeneous and isotropic perfect fluid spacetimes in Einstein-Gauss-Bonnet (EGB) gravity. We solve the modified field equations with…
Generating exact polytropes in non-conservative unimodular geometries
Sudan Hansraj, Chevarra Hansraj, Njabulo Mkhize +2
The trace-free Einstein equations contain one equation less than the complete field equations. In a static and spherically symmetric spacetime, the number of field equations is thu…
What makes a shear-free spherical perfect fluid be inhomogeneous with tidal effects?
Jonathan Hakata, Rituparno Goswami, Chevarra Hansraj +1
This is an important and natural question as the spacetime shear, inhomogeneity and tidal effects are all intertwined via the Einstein field equations. However, as we show in this…
The Buchdahl Bound Denotes The Geometrical Virial Theorem
Naresh Dadhich, Rituparno Goswami, Chevarra Hansraj
In this paper, we geometrically establish yet another correspondence between Newtonian mechanics and general relativity by connecting the Buchdahl bound and the Virial theorem. Buc…
A semi-tetrad decomposition of the Kerr spacetime
Chevarra Hansraj, Rituparno Goswami, Sunil D. Maharaj
In this paper we perform a semi-tetrad decomposition of the Kerr spacetime. We apply the 1+1+2 covariant method to the Kerr spacetime in order to describe its geometry outside the…
