Speckle interferometry at the U.S. Naval Observatory. XXII. (2017)

Keywords : binaries general - binaries: visual - stars: individual (BD+32 1731, HD 183063, HD 193651) - techniques: interferometric

Abstract:The results of 4747 intensified CCD observations of double stars, made with the 26 inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system represents a combination of over 2000 short-exposure images. These observations are averaged into 2667 mean relative positions and range in separation from 0.328" to 95.9", with a median separation of 8.673". Eight orbits are improved. This is the 22nd in this series of papers and covers the period 2016 January 4 through 2016 December 29. ...(more)

This is the 22nd in a series of papers from the U.S. Naval Observatory's speckle interferometry program, presenting results of observations obtained at the USNO 26 inch telescope in Washington, DC (see, most recently, Mason et al. 2017, J/AJ/153/20). From 2016 January 4 through December 29, the 26 inch telescope was used on 67 of 216 (31%) scheduled nights. Individual nightly totals varied substantially, from 7 to 200 observations per night (mean 71.3). The results yielded 4747 observations (pointings of the telescope) and 4795 resolutions (pairs measured).
