Mid-infrared Period - luminosity Relations of RR Lyrae Variables via Color-transformed Data

Пн, Январь 27, 2025 - 14:37

We derive RR Lyrae period - metallicity - mid-infrared luminosity relations in the WISE W1 and W2 bands based on intensity-mean W1 and W2 magnitudes computed from intensity-mean Gaia G_(BP) and G_(RP) magnitudes and known metallicity..
