Abstract:
We report on the results of speckle observations at the 4.1m SOAR
telescope in 2010 and 2011. A total of 639 objects were observed. We
give 562 measurements of 418 resolved binaries, including 21 pairs
resolved for the first time, and upper detection limits for 221
unresolved stars. New orbital elements have been determined for 42
physical pairs, of which 22 are first-time calculations; the rest are
corrections, sometimes substantial. Linear elements are calculated for
nine apparently optical doubles. We comment on new pairs, new orbital
solutions, and other remarkable objects.
Description:
The observations were obtained with the high-resolution camera (HRCam)
during two runs (2010 December 18-19 and 2011 January 13-14) at the
4.1m SOAR telescope. This work also includes double-star measures done
occasionally during SAM (SOAR Adaptive Module) commissioning runs in
2010 and 2011.
