cds-question@unistra.frmultiple-starsmillimeter-astronomyphotometrysubmillimeter-astronomyWe have conducted a survey of 17 wide (>100 AU) young binary systems in Taurus with the Atacama Large Millimeter Array (ALMA) at two wavelengths. The observations were designed to measure the masses of circumstellar disks in these systems as an aid to understanding the role of multiplicity in star and planet formation. The ALMA observations had sufficient resolution to localize emission within the binary system. Disk emission was detected around all primaries and 10 secondaries, with disk masses as low as 10^-4^ M_{sun}_. We compare the properties of our sample to the population of known disks in Taurus and find that the disks from this binary sample match the scaling between stellar mass and millimeter flux of F_mm_ \propto M_*_^1.5-2.0^ to within the scatter found in previous studies. We also compare the properties of the primaries to those of the secondaries and find that the secondary/primary stellar and disk mass ratios are not correlated; in three systems, the circumsecondary disk is more massive than the circumprimary disk, counter to some theoretical predictions.2014ApJ...784...62Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/784/62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/696/L84 : Primordial circumstellar disks in binary systemsJ/ApJ/703/1511 : Wide binaries in Taurus and Upper Sco (Kraus+, 2009)J/ApJ/751/115 : Millimeter emission from Taurus binary systems (Harris+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/784/62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/784/62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/784/62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/784/62https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/784/62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/784/62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/784/62/table4 (Positional Fitting Results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/784/62/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/784/62/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/784/62/table4?GETtext/xml+votable180.050000true66.72312526.114973060.0055555555555555566/1031 1037 1039 1048 1050 1073 1074 1124 1136 1159 1168 23542 23549 24300https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/784/62?format=asciiRadiodefaultJ/ApJ/784/62/table4Positional Fitting ResultsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
