Description
RR Lyrae stars are powerful pulsating tracers of the Milky Way’s structure and stellar populations. We present a catalog of 315 RR Lyrae light curves combining Gaia DR3 with J-VAR DR1 observations from the JAST80 telescope at the Observatorio Astrofísico de Javalambre, complemented by J-PLUS multi-filter photometry. We will also present preliminary results from the analysis of Gaia–J-PLUS RR Lyrae light curves, highlighting trends in multi-band amplitudes and their potential for population studies. This work illustrates the value of combining current surveys as a pathfinder for future Gaia-based and GaiaNIR astrometric science.
