TL;DR: In this article, the authors report on speckle observations of binary stars carried out at the WIYN Telescope over the period from 2010 September through 2012 February, providing relative astrometry for 2521 observations of 883 objects, 856 of which are double stars and 27 of which were triples.

TL;DR: Differential astrometry measurements from the Palomar Highprecision Astrometric Search for Exoplanet Systems have been combined with lower precision single-aperture measurements covering a much longer timespan (from eyepiece measurements, speckle interferometry, and adaptive optics) to determine improved visual orbits for 20 binary stars.

TL;DR: In this article, the authors report on speckle observations of binary stars carried out at the WIYN Telescope over the period from September 2010 through February 2012, providing relative astrometry for 2521 observations of 883 objects, 856 of which are double stars and 27 of which were triples, and they find that the individual separations obtained have linear measurement uncertainties of approximately 2 mas, and photometry is uncertain to approximately 0.1 magnitudes in general.

TL;DR: In this article, the authors report 370 measures of 170 components of binary and multiple star systems, obtained from speckle imaging observations made with the Differential Speckle Survey Instrument at Lowell Observatory's Discovery Channel Telescope in 2015 through 2017.

The 2001 US Naval Observatory Double Star CD-ROM. II. The Fifth Catalog of Orbits of Visual Binary Stars
TL;DR: The Fifth catalog of Orbits of Visual Binary Stars as mentioned in this paper contains 1465 orbits of 1430 visual binary stars from the 1930s to the 1980s, with the same grading scheme as in earlier catalogs, although the grading scheme was modified to be more objective.

Orbital coplanarity in solar-type binary systems: Implications for planetary system formation and detection
TL;DR: In this article, the equatorial inclinations of solar-type stars within visual binary systems are computed by combining v sin i measurements with rotational period information, or with expected rotational velocities based upon the age of the star in question, and the results are extended to planetary systems in order to determine the appropriateness of basing planetary search strategies upon a parent star's equatorial inclination.

TL;DR: In this paper, the median separation of 487 binary star systems with speckle interferometry with the 4 m telescope on Kitt Peak was determined, and a known wide pair and a previously undetected component to a high-velocity star were detected.
