# Neutron Stars, Ungravity, and the I-Love-Q relation

## TL;DR

This paper investigates how ungravity theories influence neutron star properties, deriving observational bounds and analyzing the impact on universal I-Love-Q relations for various neutron star masses.

## Contribution

It introduces a novel analysis of neutron stars within an ungravity framework, establishing bounds on model parameters and exploring effects on key dynamic properties and universal relations.

## Key findings

- Bounds on ungravity parameters from observational data
- Alterations in neutron star moments of inertia, Love numbers, and quadrupole moments due to ungravity
- Validation of the I-Love-Q relation within the ungravity context

## Abstract

In this work, we study neutron stars (NSs) in an ungravity (UG) inspired model. We examine the UG effects on the static properties of the selected NSs, in different mass and radius regimes, i.e., mini, moderate, and heavy NSs, using a polytropic equation of state approach. Based on the observational data, we obtain bounds on the characteristic length and scaling dimension of the UG model. Furthermore, we obtain dynamic properties, such as inertial moment (I), Love number (Love), and quadrupole moment (Q) of a slowly rotating NS in the presence of the exterior gravity and ungravity fields. The UG model is also examined with respect to the I-Love-Q universal relation.
