Gravitationally collapsing stars in f(R) gravity
Suresh C. Jaryal, Ayan Chatterjee
Abstract
Abstract The gravitational dynamics of a collapsing matter configuration which is simultaneously radiating heat flux is studied in f ( R ) gravity. Three particular functional forms in f ( R ) gravity are considered to show that it is possible to envisage boundary conditions such that the end state of the collapse has a weak singularity and that the matter configuration radiates away all of its mass before collapsing to reach the central singularity.
