Observations of Binary Stars with the Differential Speckle Survey Instrument. II. Hipparcos Stars Observed in 2010 January and June
The results of 497 speckle observations of Hipparcos stars and selectedother targets are presented. Of these, 367 were resolved into componentsand 130 were unresolved. The data were obtained using the DifferentialSpeckle Survey Instrument at the WIYN 3.5 m Telescope. (The WIYNObservatory is a joint facility of the University of Wisconsin-Madison,Indiana University, Yale University, and the National Optical AstronomyObservatories.) Since the first paper in this series, the instrument hasbeen upgraded so that it now uses two electron-multiplying CCD cameras.The measurement precision obtained when comparing to ephemeris positionsof binaries with very well known orbits is approximately 1-2 mas inseparation and better than 0fdg6 in position angle. Differentialphotometry is found to be in very good agreement with Hipparcos measuresin cases where the comparison is most relevant. We derive preliminaryorbits for two systems.
