Abstract:
Results of 974 speckle observations of 546 binary stars are presented.
Observations were obtained at the WIYN 3.5m Telescope at Kitt Peak
National Observatory during the time interval from 2007 January to
2008 June. In all cases, the relative separation and position angle of
the components are measured, and the magnitude difference is
determined in 809 cases. The precision of the results as judged from
repeat observations and objects with very well-determined orbits is
similar to previous papers in this series, namely ∼3mas in separation
and <1° in position angle in most cases. Similarly, the photometric
precision remains consistent with previous WIYN speckle data, on
average ∼0.1mag per observation. Six systems of special interest are
discussed.
Description:
All of the observations discussed below were obtained at the WIYN 3.5m
Telescope, located at Kitt Peak National Observatory. We present
results from six observing runs that occurred between 2007 January and
2008 June, where the instrumentation used was the RYTSI speckle camera
and one of the two PIXIS 2048B CCDs now used in the DSSI.
