Název v původním jazyce

Dissipative gravitational collapse in f(R) gravity with anisotropy and inhomogeneity density

Popis výsledku v původním jazyce

In this article, we will explore the collective impact of Starobinsky model and horizon function in the proximity of f(R) the theory of gravity (R is the Ricci scalar) in the dissipative gravitational collapse. Our investigation delves into the radiating stellar model with string density accompanied by an exterior Vaidya spacetime in f(R) gravity. We precisely explain the boundary conditions and non-vanishing radial pressure due to heat flux in the presented model. In the model presented here, we have used the horizon function with Starobinsky and Krori and Barua assumptions in the presence of strings to demonstrate the end states of black hole collapse. Graphical analysis is also presented to strengthen our arguments.
