Abstract:
Binary stars ubiquitous throughout the Universe are important. Contact
binaries (CBs) possessing period-luminosity (PL) relations could be
adopted as distance tracers. The PL relations of CBs are influenced by
metallicity abundance and color index, which are connected to both the
radius and luminosity of stars. Here we propose fine relations of the
period-luminosity-metallicity-color (PLZC) from the ultraviolet to
infrared bands based on current surveys. The accuracy of the distance
estimation is 6% and 8%, respectively, depending on the PLZC relations
of the CBs in the infrared and optical bands of the collected data.
PLZC models are still more accurate than PLC models in determining
intrinsic luminosity, notwithstanding their limited improvement.
Meanwhile, these relations based on synthetic photometry are also
calibrated. On the basis of the synthetic photometry, a 6% accuracy of
distance is estimated. The measured or synthetic data of PLZC or PLC
relations in infrared bands comes first in the list of suggestions for
distance estimations and is followed by the measured data of optical
bands.
Description:
The data of contact binaries (CBs) analyzed in this work are collected
based on the General Catalogue of Variable Stars (Version GCVS 5.1;
see B/gcvs), the All-Sky Automated Survey for Supernovae (ASAS-SN;
Jayasinghe+ 2019; see II/366), and the Northern Catalina Sky Survey
(CSS; Sun+ 2020, J/ApJS/247/50).
The photometric data analyzed in this work cover the bands of Gaia
Data Release 3 (DR3; Gaia Col. see I/357), Wide-field Infrared Survey
Explorer (WISE; see II/311), and Galaxy Evolution Explorer (GALEX;
see II/335).
The metallicity abundance ([Fe/H]) and effective temperature (Teff) of
the CBs are obtained through crossmatching with the catalogs of LAMOST
Data Release 9 (see V/162).
