Description

We generalise the anisotropic core–envelope model of the super-dense star to kappa-deformed space-time (a non-commutative space-time) and study the modifications due to the existence of a minimal length. We formulate Einstein’s field equation in the kappa-deformed space-time and solve it to obtain the anisotropic core–envelope model, describing the super-dense star, in kappa deformed space-time. The solutions will yield the kappa-deformed law of density variation, the expression for the radial as well as tangential pressures in the kappa-deformed space-time. We also derive the kappa-deformed strong energy conditions and obtain a bound on the deformation parameter.
