I-Love-Q relations for Neutron Stars with Dark Energy

TL;DR

This paper explores how dark energy affects neutron star properties and confirms that the universal I-Love-Q relations remain valid even with dark energy influences, broadening their applicability.

Contribution

It extends the I-Love-Q relations to neutron star models incorporating dark energy, showing their universality persists.

Findings

I-Love-Q relations hold for neutron stars with dark energy.

Dark energy influences neutron star equations of state.

Universal relations remain valid despite dark energy presence.

Abstract

The influence of a dark energy fluid on the equation of state of neutron stars is investigated. A detailed analysis is conducted for such models, including the computation of the moment of inertia, the quadrupole moment, and the tidal Love number. The results demonstrate that these quantities are interconnected through the well-known equation of state independent I-Love-Q relations. This work extends the applicability of these universal relations to a broader class of neutron star models.
