# Gravitational Waves from Compact Dark Objects in Neutron Stars

## TL;DR

This paper explores how oscillations of compact dark objects within neutron stars could generate detectable gravitational waves, with potential observability by LIGO for certain mass ranges.

## Contribution

It introduces the idea that CDO oscillations inside neutron stars can produce gravitational waves detectable by current observatories.

## Key findings

- GW frequency range 3-5 kHz
- LIGO sensitivity to CDO masses > 10^{-8} solar masses
- GW strain amplitude depends on CDO mass

## Abstract

Dark matter could be composed of compact dark objects (CDOs). We find that the oscillation of CDOs inside neutron stars can be a detectable source of gravitational waves (GWs). The GW strain amplitude depends on the mass of the CDO, and its frequency is typically in the range 3-5 kHz as determined by the central density of the star. In the best cases, LIGO may be sensitive to CDO masses greater than or of order $10^{-8}$ solar masses.
