BINARY STAR ORBITS. IV. ORBITS OF 18 SOUTHERN INTERFEROMETRIC PAIRS
Astronomical Journal, 2010 First orbits are presented for 3 interferometric pairs and revised solutions for 15 others, based in part on first results from a recently initiated program of speckle interferometric observations of neglected southern binaries. Eight of these systems contain additional components, with multiplicity ranging up to 6.

Astronomical Journal, 2001 The Third Catalog of Interferometric Measurements of Binary Stars includes all published measures of binary and multiple star systems obtained by high-resolution techniques (speckle interferometry, photoelectric occultation timings, etc.), as well as negative examinations for duplicity, as of 2001 January 1. This catalog is one of four USNO double star

Speckle interferometric measurements of binary stars. VII.
Astrophysical Journal, Supplement Series, 1982 Four hundred-forty measurements of 232 binary stars observed during 1981 by means of speckle interferometry with the 4-m telescope at KPNO are represented. Newly resolved systems include Xi-1 Cet, Rho Her A, HD 187321, and 59 Cyg A.

Preliminary Orbital Elements of Four Interferometric Binary Stars [PDF]
Astronomical Journal, 2005 We present preliminary orbital elements for the four interferometric binary star systems WDS 01017+2518, 02262+3428, 02442-2530, and 11268-5310. For all stars these are the first orbits that have been published. The data are accompanied by uncertainty estimates, residuals, and ephemerides, as well as dynamical parallaxes and individual star masses.

Astronomical Journal, 2002 We report spectroscopic and interferometric observations of the moderately metal-poor double-lined binary system HD 195987, with an orbital period of 57.3 days. By combining our radial-velocity and visibility measurements, we determine the orbital elements and derive absolute masses for the components of MA = 0.844 ± 0.018 M⊙ and MB = 0.6650 ± 0.0079 M⊙

Interferometric studies of disk-eclipsed binary star systems
Proceedings of SPIE, 2016As sky surveys continue to document an increasing number of transient celestial phenomena, an intriguing subset of objects are emerging that show variations in brightness, interpreted as the transit of a circumstellar disk in front of a companion star in a binary system.

Sub-percent binary star masses and distances from interferometric observations
Proceedings of the International Astronomical Union, 2022AbstractOur knowledge of stellar evolution relies on constraints provided by measurements of the physical stellar properties such as the mass, effective temperature, and radii. The most fundamental parameter, the stellar mass, is rarely available or has a low accuracy, providing poor constraints on the stellar structure and evolution.
