All Tables

Table 1: Results from the ADONIS adaptive optics survey among 199 Sco OB2 member stars. The columns list: Hipparcos number, observed J, H and $K_{\rm S}$ magnitude, spectral type of the primary, angular separation (arcsec), position angle (degrees; measured from North to East), and status (p = primary/single star; c = companion star; nc = new companion star; b = background star). The last two columns list the subgroup of which the system is a member (US = Upper Scorpius; UCL = Upper Centaurus Lupus; LCC = Lower Centaurus Crux), and a flag in case the observing conditions were not photometric. The Hipparcos member stars HIP77315 and HIP77317 are a common proper motion pair (see the Double Star Catalog). In this paper the two stars are treated as separate primaries and not as one system. Table 1 is presented in its entirety in the electronic edition of the journal. A portion is shown here for guidance regarding its form and content.
Table 2: References to literature data with spectroscopic, astrometric, eclipsing, and visual binaries in Sco OB2. Using these data we find that 33 out of the 74 candidate companion stars in our dataset were already documented in literature, while 41 were previously unknown.
Table 3: Binarity data for Sco OB2, showing the number of companion stars found with the different techniques. Literature data and the new companion stars described in this paper are included. The terms "visual'', "astrometric'', and "spectroscopic'' pertain only to available observations and not to in intrinsic properties of the systems. Note that each companion of a multiple system is included individually.
Table 4: Multiplicity among Hipparcos members of Sco OB2. The columns show the subgroup names (Upper Scorpius; Upper Centaurus Lupus; Lower Centaurus Crux), their distances (see de Zeeuw et al. 1999), the ages (de Geus et al. 1989; Preibisch et al. 2002, for US; Mamajek et al. 2002 for UCL and LCC), the number of known single stars, binary stars, triple systems and N>3 systems, and the binary statistics (see Sect. 5.2) .
