# Gravitational waves from compact dark matter objects in the solar system

## TL;DR

This paper investigates the potential gravitational wave signals from close binary dark matter objects within the solar system, setting new constraints on their properties using LIGO and VIRGO data.

## Contribution

It presents the first search for gravitational waves from compact dark matter binaries inside the solar system, establishing new mass and separation limits.

## Key findings

- Excluded binaries with separations around 300 m near the Sun's center.
- Set mass limits for dark matter objects down to 10^{-9} solar masses.
- Demonstrated sensitivity surpassing previous extragalactic searches by eight orders of magnitude.

## Abstract

Dark matter could be composed of compact dark objects (CDOs). A close binary of CDOs orbiting in the interior of solar system bodies can be a loud source of gravitational waves (GWs) for the LIGO and VIRGO detectors. We perform the first search ever for this type of signal and rule out close binaries, with separations of order 300 m, orbiting near the center of the Sun with GW frequencies (twice the orbital frequency) between 50 and 550 Hz and CDO masses above $\approx 10^{-9} M_\odot$. This mass limit is eight orders of magnitude lower than the mass probed in a LIGO search at extra galactic distances.
