Gravastar configuration in non-conservative Rastall gravity

Abstract In the present article, we have presented exact solutions of gravastar with Kuchowicz metric potential in background non-conservative Rastall gravity. Within context Mazur-Mottola’s [1, 2] concept Bose–Einstein condensation to gravitational systems, grvastar structure consists three layers: interior part, intermediate part (i.e., thin shell) and exterior part. All gravastar’s been derived aid by considering isotropic matter distribution. For shell (filled ultra-relativistic stiff fluid) different parameters like length, energy, entropy surface redshift calculated, which show stability our proposed model. Interestingly, all results are obtained without taking approximation i.e., 0 < e − ν ≡ h ≪ 1. The is absolutely a vacuum characterized Schwarzschild geometry give output form non-singular results. Generally, main purpose this work obtain exact, non-singular, horizon free, stable model achieved these goals presence parameter.
