Anisotropic strange star with de Sitter spacetime

TL;DR

This paper models anisotropic strange stars within a de Sitter spacetime framework, incorporating a cosmological constant to analyze their structure, and finds compatibility with known physical features of such stars.

Contribution

It introduces a novel de Sitter spacetime model for anisotropic strange stars using the Krori-Barua solution, considering the cosmological constant at a stellar scale.

Findings

Cosmological constant inclusion aligns with physical features of strange stars.

The model provides analytical solutions consistent with known star properties.

De Sitter spacetime effectively describes anisotropic strange star structure.

Abstract

Stars can be treated as self-gravitating fluid. Krori and Barua (1975) gave an analytical solutions to that kind of fluids. In this connection, we propose a de-Sitter model for an anisotropic strange star with the Krori-Barua spacetime. We incorporate the existence of cosmological constant in a small scale to study the structure of anisotropic strange stars and come to conclusion that this doping is very much compatible with the well known physical features of strange stars.
