Abstract:
We report the results of speckle runs at the 4.1m Southern
Astronomical Research telescope in 2012 and 2013. A total of 586
objects were observed. We give 699 measurements of 487 resolved
binaries and upper detection limits for 112 unresolved stars. Eleven
pairs (including one triple) were resolved for the first time. Orbital
elements have been determined for the first time for 13 pairs; orbits
of another 45 binaries are revised or updated.
Description:
The observations reported here were obtained (in 2012 Oct 29-30, 2012
Dec 1-2, 2013 Jan 28-29, 2013 Feb 15-16, 2013 Mar 27, 2013 Jun 22,
2013 Sep 25-27) with the high-resolution camera (HRCam)-a fast imager
designed to work at the 4.1m SOAR telescope located at Cerro Pachon in
Chile. The camera was mounted on the SOAR Adaptive Module (SAM).
