Nonlinear completions of the Ricci coupling in black-hole scalarization
Subrat Parida
We study spontaneous scalarization of static, spherically symmetric black holes in scalar--Gauss--Bonnet gravity with a Ricci coupling that nonl…

On Super-Hyperbolic Wormhole Geometries and their Deformations
Subrat Parida
In this study, we developed a unified geometric and relativistic framework for a new family of traversable wormholes constructed from a super-hyperbolic deformation of the classica…

Closed-form representations of extended astrophysical thermonuclear functions
Subrat Parida
Reaction rate determination is an essential problem in the theories of cosmological and stellar nucleosynthesis. I investigate the closed-form analytic evaluation of thermonuclear…
