cds-question@unistra.fropen-star-clustersmultiple-starsinfrared-photometryWe introduce a new binary detection technique, Binary INformation from Open Clusters using SEDs (binocs), which we show is able to determine reliable stellar multiplicity and masses over a much larger mass range than current approaches. This new technique determines accurate component masses of binary and single systems of the open clusters' main sequence by comparing observed magnitudes from multiple photometric filters to synthetic star spectral energy distributions (SEDs), allowing us to systematically probe the binary population for low-mass stars in clusters for eight well-studied open clusters. We provide new deep, infrared photometric catalogs (1.2-8.0 {mu}m) for the key open clusters NGC 1960 (M36), NGC 2099 (M37), NGC 2420, and NGC 2682 (M67), using observations from NOAO/NEWFIRM and Spitzer/IRAC. Using these deep multiwavelength catalogs, the binocs method is applied to these clusters to determine accurate component masses for unresolved cluster binaries. We explore binary fractions as a function of cluster age, Galactic location, and metallicity.2021AJ....161..160Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/ocl : Optically visible open clusters and Candidates (Dias+, 2002-2015)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)II/316 : UKIDSS-DR6 Galactic Plane Survey (Lucas+ 2012)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+A/357/471 : BV and proper motions in NGC 1960 & NGC 2194 (Sanner+, 2000)J/AJ/126/2922 : Astrometry and membership in NGC 188 (Platais+, 2003)J/PASP/116/1012 : A star catalog for the open cluster NGC 188 (Stetson+, 2004)J/AJ/129/656 : Infrared photometry of NGC 6791 (Carney+, 2005)J/AJ/132/1669 : Wide-field CCD phot. around nine open clusters (Sharma+,2006)J/AJ/135/2264 : Stellar radial velocities in NGC 188 (Geller+, 2008)J/ApJ/675/1233 : gri photometry in M37 (NGC 2099) (Hartman+, 2008)J/A+A/484/609 : BVI photometry and proper motions in M67 (Yadav+, 2008)J/ApJ/700/523 : Galactic star clusters in SDSS.
