A first view with GAIA on KIC 8462852 - distance estimates and a comparison to other F stars

Distance estimates from Gaia parallax and expected luminosities are compared for KIC 8462852. Gaia DR1 yields a parallax of $2.55\pm0.31$mas, that is a distance of $391.4\substack{+53.6 \\ -42.0}$pc, or $391.4\substack{+122.1 \\ -75.2}$pc including systematic uncertainty. The distance estimate based on the absolute magnitude of an F3V star and measured reddening is $\sim454\pm35$pc. Both estimates agree within $<1σ$, which only excludes some of the most extreme theorized scenarios for KIC 8462852. Future Gaia data releases will determine the distance to within 1% and thus allow for the determination a precise absolute luminosity.
