Abstract

Dark matter could be composed of compact dark objects (CDOs). We find that a
close binary of CDOs orbiting {\it inside} solar system bodies can be a loud
source of gravitational waves (GWs) for the LIGO and VIRGO detectors. An
initial search of data from the first Advanced LIGO observing run (O1),
sensitive to $h_0\approx 10^{-24}$, rules out close binaries orbiting near the
center of the Sun with GW frequencies (twice the orbital frequency) between 50
and 550 Hz and CDO masses above approximately 10^{-9} M_sun.
