KISOGP: 7055 eclipsing binaries with KWFC
Listed in IVOA Registry (Virtual Observatory)
We present a catalog of eclipsing binaries in the northern Galactic plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP).
Description
We visually identified 7055 eclipsing binaries spread across ~330deg^2^, including 4197 W Ursa Majoris/EW-type, 1458 {beta}Lyrae/EB-type, and 1400 Algol/EA-type eclipsing binaries. For all systems, I-band light curves were used to obtain accurate system parameters.
We derived the distances and extinction values for the EW-type objects from their period-luminosity relation. We also obtained the structure of the thin disk from the distribution of our sample of eclipsing binary systems, combined with those of high-mass star-forming regions and Cepheid tracers. We found that the thin disk is inhomogeneous in number density as a function of Galactic longitude.

Using this new set of distance tracers, we constrain the detailed structure of the thin disk. Finally, we report a global parallax zero-point offset of {Delta}{pi}=-42.1{+/-}1.9(stat.){+/-}12.9(syst.){mu}as between our carefully calibrated EW-type eclipsing binary positions and those provided by Gaia Early Data Release 3. Implementation of the officially recommended parallax zero-point correction results in a significantly reduced offset.
Additionally, we provide a photometric characterization of our EW-type eclipsing binaries that can be applied to further analyses.
