Statistical Analysis of a Comprehensive List of Visual Binaries
Visual binary stars are the most abundant class of observed binaries. The most comprehensive list of data on visual binaries compiled recently by cross-matching the largest catalogues of visual binaries allowed a statistical investigation of ...

The Mass-Ratio Distribution of Visual Binary Stars [PDF]
The selection effects that govern the observations of Visual Binary Stars are in- vestigated, in order to obtain a realistic statistical distribution of the mass-ratio q = Msec=Mprim.

Visual Binary Stars: Data to Investigate Formation of Binaries
Statistics of orbital parameters of binary stars as well as statistics of their physical characteristics bear traces of star formation history. However, statistical investigations of binaries are complicated by incomplete or missing observational data ...

Some Photometric Characteristics of Population II Orbital Visual Binary Stars [PDF]
A MV ,B−V diagram for metal-deficient, kinematically selected thick disk and halo visual binary stars with known orbits is presented. The magnitude differences Δm between the components are analyzed.

Precise orbital parameters,masses, and parallax of the subgiant binary system 12 Persei: a combined spectroscopic–interferometric analysis [PDF]
In this work, we determine the orbital parallax of 12 Persei from a combined spectroscopic and interferometric solution and compare it with those from Gaia and Hipparcos to assess their consistency.

Orbits of Binary Stars: from Visual Measures to Speckle Interferometry
Knowledge of the orbits of visual binary stars has always been one of the fundamentals of astronomy. Based historically on the visual measures, nowadays the orbits rely more (or exclusively) on the accurate speckle data.

We present a method to identify likely visual binaries in Gaia eDR3 that does not rely on parallax or proper motion. This method utilizes the various point-spread function sizes of Two Micron All Sky Survey (2MASS)/Gaia, where at
