Abstract:
W Ursa Majoris (W UMa)-type contact binary systems (CBs) are useful
statistical distance indicators because of their large numbers. Here,
we establish (orbital) period-luminosity relations (PLRs) in 12
optical to mid-infrared bands (GBVRIJHKsW1W2W3W4) based on 183 nearby
W UMa-type CBs with accurate Tycho-Gaia parallaxes. The 1σ
dispersion of the PLRs decreases from optical to near- and
mid-infrared wavelengths. The minimum scatter, 0.16mag, implies that
W UMa-type CBs can be used to recover distances to 7% precision.
Applying our newly determined PLRs to 19 open clusters containing
W UMa-type CBs demonstrates that the PLR and open cluster CB distance
scales are mutually consistent to within 1%. Adopting our PLRs as
secondary distance indicators, we compiled a catalog of 55603 CB
candidates, of which 80% have distance estimates based on a
combination of optical, near-infrared, and mid- infrared photometry.
Using Fourier decomposition, 27318 high-probability W UMa-type CBs
were selected. The resulting 8% distance accuracy implies that our
sample encompasses the largest number of objects with accurate
distances within a local volume with a radius of 3kpc available to
date. The distribution of W UMa-type CBs in the Galaxy suggests that
in different environments, the CB luminosity function may be
different: larger numbers of brighter (longer-period) W UMa-type CBs
are found in younger environments.
