Speckle observations of visual and spectroscopic binaries. IV.
Abstract
This is the fourth paper of this series giving results of speckle observations for 22 visual and 161 spectroscopic binaries. The observations were carried out by using the 212 cm telescope of San Pedro Martir Observatory in Mexico at 7 nights from July 20 to July 26, 1991. The authors obtained fringes in power spectra of 19 visual and 11 spectroscopic binaries (6 newly resolved ones) with angular separation larger than 0″06. They introduced a new ICCD TV camera in this observation, and were able to achieve the diffraction-limit resolution of the 212 cm telescope.
