Speckle interferometry of HIPPARCOS link stars
Speckle interferometry has been carried out on 39 stars that had beenselected as provisionally suitable for linking Hipparcos positionalmeasurements to an extragalactic reference frame by Space Telescope. TheImperial College, London, speckle interferometer and the autocorrelatoron the Anglo-Australian 3.9-m telescope are used. The result is thatabout 30 percent of the stars selected turned out to be confirmed orsuspected multiple stars in the range 0.03-0.7 arcsec.
