First loosely coherent search for continuous gravitational wave sources with substellar companions in the Orion spur

We report on the first loosely coherent search for binary systems. We searched 0.06 rad disk in the Orion spur, covering gravitational wave frequencies from 100 to 700 Hz and frequency derivatives between -1e-11 to 1e-11 Hz/s. A follow-up was performed, which found no outliers. An atlas of results from the first stage of the search is made publicly available.
