Abstract:
Many binary stars observed at the SOR during adaptive optics calibration on the 3.5 m telescope turn out to be ‘off orbit’, especially those from the ‘All Binaries’ spreadsheet (as opposed to the ‘Calibration Binaries’ spreadsheet) that I made available at the AMOS Conference last year. In some cases new companions have been discovered. New positions and relative magnitudes will be reported, and for some, new orbits. At the separations available through AO, most binaries show motion, making the best calibrators those with derived orbits. The conclusion is that many new binary discoveries can be made by simply turning on AO in the IR.
Date of Conference: September 11-14, 2012
