Gravitationally collapsing stars in f(R) gravity

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.

Automated summary

The gravitational dynamics of a collapsing matter configuration radiating heat flux in f(R) gravity is studied with three specific functional forms to show that it is possible to have boundary conditions where the collapse ends with a weak singularity and all mass is radiated away before reaching the central singularity.
