Speckle observations of double stars with PISCO at Pic du midi measurements in 1998. (2000)

Keywords : astrometry - binaries visual - stars: fundamental parameters

Abstract:We present astrometric measurements of binary stars based on speckle observations of 164 independent sequences of observations (~10^4^ frames each) made with the PISCO speckle camera at Pic du Midi. These measurements concern 147 objects, of which 134 were found to be double with a separation in the range 0.1"-1.0". These objects were mainly selected among grade 3 orbits to improve the accuracy of their orbits and to constrain their masses. We discovered the binarity of 59 Aql with an angular separation of 0.09"+/-0.01". ...(more)
