Collapsing spherical stars in f(R) gravity
Rituparno Goswami, Anne Marie Nzioki, Sunil. D. Maharaj +1
We perform a careful investigation of the problem of physically realistic gravitational collapse of massive stars in f(R)-gravity. We show that the extra matching conditions that a…
Vibrating Black Holes in f(R) gravity
Anne Marie Nzioki, Rituparno Goswami, Peter K. S. Dunsby
We consider general perturbations of a Schwarzschild black holes in the context of f(R) gravity. A reduced set of frame independent master variables are determined, which obey two…
A Geometrical Approach to Strong Gravitational Lensing in f(R) Gravity
Anne Marie Nzioki, Peter K. S. Dunsby, Rituparno Goswami +1
We present a framework for the study of lensing in spherically symmetric spacetimes within the context of f(R) gravity. Equations for the propagation of null geodesics, together wi…
