# Exact solution of anisotropic compact stars via. mass function

## TL;DR

This paper derives exact anisotropic star solutions in general relativity, modeling compact objects like strange stars, and compares these models with observational data to better understand their internal structure.

## Contribution

It presents new exact solutions for anisotropic compact stars, linking metric potentials with a specific mass function, and applies these models to observed strange star candidates.

## Key findings

- Models fit observational data of strange stars
- Provides explicit anisotropic solutions for compact objects
- Potential to explain physics of self-gravitating astrophysical bodies

## Abstract

The interest in studying relativistic compact objects play an important role in modern astrophysics with an aim to understand several astrophysical issues. It is therefore natural to ask for internal structure and physical properties of specific classes of compact star for astrophysical observable, and we obtain a class of new relativistic solutions with anisotropic distribution of matter for compact stars. More specifically, stellar models, described by the anisotropic fluid, establish a relation between metric potentials and generating a specific form of mass function are explicitly constructed within the framework of General Relativity. New solutions that can be used to model compact objects which adequately describe compact strange star candidates like SMC X-1, Her X-1 and 4U 1538-52, with observational data taken from Gangopadhyay et al. [1]. As a possible astrophysical application the obtained solution could explain the physics of self-gravitating objects, might be useful for strong-field regimes where data are currently inadequate.
