Photometric Metallicity and Distance Estimates for ∼70,000 RR Lyrae Stars from the Zwicky Transient Facility
Utilizing Zwicky Transient Facility (ZTF) data and existing RR Lyrae stars (RRLs) catalogs, this study achieves the first calibration of the P − ϕ _31 − R _21 − [Fe/H] and P − ϕ _31 − A _2 − A _1 − [Fe/H] relations in the ZTF photometric system for RRab and RRc stars. We also recalibrate the period–...
