First speckle interferometry at SOAR telescope with electron-multiplication CCD.

TOKOVININ A. and CANTARUTTI R.

Abstract (from CDS):

A simple camera with electron-multiplication CCD, fast frame rate, and a pixel scale of 15 mas is described. This instrument was tested at the SOAR 4-m telescope in the speckle-interferometry regime. The data were processed by the standard speckle algorithm permitting derivation of binary-star parameters. We observed 29 objects with separations from 21 mas to 1.32{Prime}, mostly southern binaries with known orbits. Some pairs require orbit revision. Two spectroscopic binaries HIP 9631 and HIP 11072 and the astrometric binary For are resolved for the first time, while three objects were unresolved.
