Photometric Metallicity and Distance Estimates for ∼136,000 RR Lyrae Stars from Gaia Data Release 3

Photometric Metallicity and Distance Estimates for ∼136,000 RR Lyrae Stars from Gaia Data Release 3

We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric metallicity and distance estimates from our newly calibrated P – ϕ _31 – R _21 –[Fe/H]/ P – R _21 –[Fe/H] and G -band absolute magnitude–metallicity relations. The P – ϕ _31 – R _21 –[Fe/H] and P – R _21 –[Fe/H] relations...
