A first view with GAIA on KIC 8462852 - distance estimates and a comparison to other F stars
Abstract
Distance estimates from Gaia parallax and expected luminosities are compared for KIC 8462852. Gaia DR1 yields a parallax of 2.550.31mas, that is a distance of 391.4+53.6 \\ -42.0pc, or 391.4+122.1 \\ -75.2pc including systematic uncertainty. The distance estimate based on the absolute magnitude of an F3V star and measured reddening is 45435pc. 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.
