cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryWe present new near-infrared (NIR), JHKs, time-series observations of RR-Lyrae variables in the Messier-3 (NGC5272) globular cluster using the WIRCam instrument at the 3.6m Canada-France-Hawaii Telescope. Our observations cover a sky area of ~21'x21' around the cluster center and provide an average of 20 epochs of homogeneous JHKs-band photometry. New homogeneous photometry is used to estimate robust mean magnitudes for 175 fundamental-mode (RRab), 47 overtone-mode (RRc), and 11 mixed-mode (RRd) variables. Our sample of 233 RR-Lyrae variables is the largest thus far obtained in a single cluster with time-resolved, multiband NIR photometry. NIR-to-optical amplitude ratios for RR-Lyrae in Messier-3 exhibit a systematic increase moving from RRc to short-period (P<0.6day) and long-period (P>~0.6day) RRab variables. We derive JHKs-band period-luminosity relations for RRab, RRc, and the combined sample of variables. Absolute calibrations based on the theoretically predicted period-luminosity-metallicity relations for RR Lyrae stars yield a distance modulus, {mu}=15.041{+/-}0.017(statistical){+/-}0.036(systematic)mag, to Messier-3. When anchored to trigonometric parallaxes for nearby RR-Lyrae stars from the Hubble Space Telescope and the Gaia mission, our distance estimates are consistent with those resulting from the theoretical calibrations, albeit with relatively larger systematic uncertainties.2020AJ....160..220Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/220CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/150 : Updated catalog of variable stars globular clusters (Clement+ 2017)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+AS/121/95 : Giant stars abundances in 24 clusters (Carretta+ 1997)J/AcA/50/221 : Astrometry of variable stars in M 3 (Bakos+, 2000)J/AJ/129/267 : RR Lyrae variables in NGC 5272 (Cacciari+, 2005)J/AJ/129/1596 : BVI photometric variability survey of M3 (Hartman+, 2005)J/MNRAS/386/2115 : Type II Cepheid and RR Lyrae variables (Feast+, 2008)J/AJ/142/187 : HST observations of 7 Pop.II variable stars (Benedict+,2011)J/MNRAS/419/2173 : Long-term photometry of M3 RR Lyrae (Jursik+, 2012)J/MNRAS/441/715 : Mid-infrared study of RR Lyrae stars (Gavrilchenko+, 2014)J/PASP/126/521 : UBVRIJHK photometry of RR Lyrae in M4 (Stetson+, 2014)J/MNRAS/447/3342 : Galactic & LMC Cepheids Fourier parameters (Bhardwaj+, 2015)J/ApJS/219/25 : Light curves of RR Lyrae stars M3 (NGC5272) (Jurcsik+, 2015)J/ApJ/807/127 : Properties of 70 RR Lyrae stars in LMC bar (Muraveva+, 2015)J/AJ/150/129 : Swift UVOT stars survey.II.
