Binary Star Orbits. VI. The Interferometric-spectroscopic Binary 73 Leo
The Astronomical JournalDiscordances in radial-velocity measurements of 73 Leonis, made more than a century ago, gave rise to the first suggestion that this fifth-magnitude star was a binary system, but it was 40 yr before an accurate investigation of the object commenced, and ...

Preliminary Orbital Elements of Four Interferometric Binary Stars [PDF]
The 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.

High Resolution Interferometric Observations of Eclipsing Binary Stars [PDF]
Symposium - International Astronomical Union, 1994 Eclipsing binary stars are of great importance in astronomy. Now, high angular resolution measurements of eclipsing stars with the Mark III Stellar Interferometer (Shao 1988) can determine not only all of the orbital parameters, but also the luminosities and color indices of the two components, and can yield precise information for the study of the ...

First speckle interferometric measurements of binary stars at the Observatorio Astrofísico Guillermo Haro [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In this paper, we present the first multiband speckle interferometric measurements of binary stars performed using the 2.1 m telescope of the Observatorio Astrofísico Guillermo Haro, Cananea, Sonora, México. We describe here FICCO: Fast Imaging Camera for Cananea Observatory, a new instrument developed to perform speckle ...
