RR Lyrae variables in Messier 53: Near-infrared Period–Luminosity relations and the calibration using Gaia Early Data Release 3

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]
