A Radial Velocity Survey of the Cygnus OB2 Association

Astrophys.J.664:1102-1120,2007 We conducted a radial velocity survey of the Cygnus OB2 Association over a 6 year (1999 - 2005) time interval to search for massive close binaries. During this time we obtained 1139 spectra on 146 OB stars to measure mean systemic radial velocities and radial velocity...
