cds-question@unistra.frmultiple-starsstellar-massesmillimeter-astronomysubmillimeter-astronomyWe present a high angular resolution millimeter-wave dust continuum imaging survey of circumstellar material associated with the individual components of 23 multiple star systems in the Taurus-Auriga young cluster. Combined with previous measurements in the literature, these new data permit a comprehensive look at how the millimeter luminosity (a rough tracer of disk mass) relates to the separation and mass of a stellar companion. Approximately one-third (28%-37%) of the individual stars in multiple systems have detectable millimeter emission, an incidence rate half that for single stars (~62%) which does not depend on the number of companions. There is a strong, positive correlation between the luminosity and projected separation (a_p_) of a stellar pair. Wide pairs (a_p_>300AU) have a similar luminosity distribution as single stars, medium pairs (a_p_{approx}30-300AU) are a factor of five fainter, and close pairs (a_p_<30AU) are ~5x fainter yet (aside from a small, but notable population of bright circumbinary disks). In most cases, the emission is dominated by a disk around the primary (or a wide tertiary in hierarchical triples), but there is no clear relationship between luminosity and stellar mass ratio.2012ApJ...751..115Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/751/115CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/745/19 : Binary systems in Taurus-Auriga (Kraus+, 2012)J/ApJ/731/8 : Multiple star formation in Taurus-Auriga (Kraus+, 2011)J/ApJ/720/480 : DISCS.
