Wormholes in Vegh--dRGT massive gravity: a null-energy transparency theorem, horizon obstruction, and exact isotropic solutions
Sudan Hansraj, Ayan Banerjee
We study static, spherically symmetric wormholes in deRham--Gabadadze--Tolley massive gravity with the spatially degenerate Vegh reference metric. The effective fluid carried by th…
Conformal flatness selects a universal isothermal attractor in pure Lovelock gravity
Sudan Hansraj
We determine the complete solution set of the conformally flat isotropic pure Lovelock field equations for every order and every admissible dimension . Conformal…
Static anisotropic stars in Lovelock gravity: Universal closed-form equations
Sudan Hansraj
A characteristic-polynomial formulation is already known for static perfect fluids in Lovelock gravity [Phys. Rev. D 113, 084008 (2026)]. We extend it to the complete anisotropic m…
Effective Constrained Scalar--Gauss--Bonnet Inflation Motivated by Gravity
G. G. L. Nashed, Sudan Hansraj, Amare Abebe
We develop an effective framework for inflation in a constrained scalar--Gauss--Bonnet theory motivated by a restricted sector of gravity. Using unified parametr…
Dynamical systems approach to stellar modelling in gravity
Sudan Hansraj, Christian G. Boehmer, Ndumiso Buthelezi
The novel proposal to invoke the split of the Ricci scalar into bulk and boundary terms in the gravitational action, opens up a new avenue of investigation into stellar dynamics. T…
