A 0.3\% calibration of the W UMa-type contact binary luminosity based on Gaia DR3
Jing Li, Xiaodian Chen, Shu Wang +3
W Ursa Majoris (W UMa)-type contact binary systems (CBs) with period--luminosity (PL) relations are valuable distance indicators. The PL relations of CBs are affected by metallicit…
