Sco OB2 association
Listed in IVOA Registry (Virtual Observatory)
To investigate the dependence of (visual) binarity characteristics on the primary component mass, we selected all stars of spectral type B in Sco OB2 association and searched for near-infrared companions to them with ADONIS and Coronograph.
Description
The data acquisition and companions measurement results are described; the mass ratio distribution f(q)=q**(-0.5) is derived using the PMS stars evolution tracks. Target stars J- and K-magnitudes are presented in Table 1; differential photometry and astrometry results for secondary companions and background sources in sky-offset fields are given in Table 2 and 3, respectively.
