Visual Binary Stars: Data to Investigate Formation of Binaries
Open Astronomy, 2016 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 ...

Orbits of Binary Stars: from Visual Measures to Speckle Interferometry [PDF]
The Astronomical JournalKnowledge 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.

Some Photometric Characteristics of Population II Orbital Visual Binary Stars [PDF]
Open Astronomy, 2003 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.

Orbital elements of six visual binary stars [PDF]
Astronomische Nachrichten, 2001 Revised orbital elements of the visual binary stars STT 515, BU 4 AB, STF 183 AB, A 207, STT 43 and A 2413 are given. Dynamical parallaxes and total masses of the systems have been calculated.

Visual binary stars with known orbits in Gaia EDR3 [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT A total of 3350 objects from the Sixth Catalog of Orbits of Visual Binary Stars (ORB6) are investigated to validate Gaia Early Data Release 3 (EDR3) parallaxes and provide mass estimates for the systems. We show that two-thirds of binaries with a separation of 0.2–0.5 arcsec are left without a parallax solution in EDR3.

Orbits of Ten Visual Binary Stars [PDF]
Chinese Journal of Astronomy and Astrophysics, 2007 We present the orbits of ten visual binary stars: WDS 01015+6922, WDS 01424–0645, WDS 01461+6349, WDS 04374–0951, WDS 04478+5318, WDS 05255–0033, WDS 05491+6248, WDS 06404+4058, WDS 07479–1212, and WDS 18384+0850. We have also determined their masses, dynamical parallaxes and ephemerides.

Orbital elements of five close visual binary stars [PDF]
Astronomische Nachrichten, 2000 Revised orbital elements of the visual binary stars STT 2, STT 4, BU 1015, STT 6 and BU 395 are given. Dynamical parallaxes and total masses of the systems have been calculated.

Pairing function of visual binary stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACTAn all-sky sample of 1227 visual binaries based on Washington Double Star catalogue is constructed to infer the initial mass function (IMF), mass ratio, and projected distance distribution with a dedicated population synthesis model. Parallaxes from Gaia DR2 and Hipparcos are used to verify the distance distribution.

Visual Orbits of Wolf–Rayet Stars. I. The Orbit of the Dust-producing Wolf–Rayet Binary WR 137 Measured with the CHARA Array [PDF]
The Astrophysical JournalClassical Wolf–Rayet (W-R) stars are the descendants of massive OB stars that have lost their hydrogen envelopes and are burning helium in their cores prior to exploding as Type Ib/c supernovae.

Classical Observations of Visual Binary and Multiple Stars [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractChanges in the double star database are highlighted, describing various methods of observation (both historically and those of the past few years) and their effectiveness in different regimes of separation space. The various niches for wide- and narrow-field work as they apply to double and multiple stars are examined and the different types of
