Speckle interferometry of nearby multiple stars. V. Position parameters measurements in 2002-2006. (2013)

Keywords : stars binaries - techniques: interferometry

Abstract:The results of speckle interferometric observations of 194 binary stars performed at the BTA 6m telescope in 2002-2006 are presented in this paper. For speckle observations we used filters with central wavelengths from 545 to 800nm and speckle camera with the fast CCD coupled with a tree-chamber intensifier. The most part of the observed systems (80 stars) - pairs, which binarity was discovered by Hipparcos satellite fo the first time. And the other stars are visual binaries and interferometric binary systems which orbital periods estimates from several to ten of the year. The pairs with slow orbital motion are included to the observation list, also. They are used for position parameters calibrations. ...(more)
