Effects of the Generalized Uncertainty Principle on Compact Stars

TL;DR

This paper explores how the generalized uncertainty principle (GUP) influences the thermodynamics and structure of compact stars, revealing that quantum gravity effects can prevent collapse and significantly reduce star radii.

Contribution

It introduces a detailed analysis of GUP effects on compact stars, highlighting quantum gravity corrections' role in stellar stability and size reduction.

Findings

Quantum gravity correction resists star collapse.

Star radii decrease exponentially with energy.

GUP effects lead to smaller compact stars.

Abstract

Based on the generalized uncertainty principle (GUP), proposed by some approaches to quantum gravity such as string theory and doubly special relativity theories, we investigate the effect of GUP on the thermodynamic properties of compact stars with two different components. We note that the existence of quantum gravity correction tends to resist the collapse of stars if the GUP parameter $\alpha$ is taking values between Planck scale and electroweak scale. Comparing with approaches, it is found that the radii of compact stars are found smaller. Increasing energy almost exponentially decreases the radii of compact stars.
