Visual Binary Stars: Data to Investigate Formation of Binaries

open access: yesOpen 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 ...

Herbig Ae/Be Visual Binaries [PDF]

open access: bronzeSymposium - International Astronomical Union, 2001
We present the results of a high-angular resolution spectro-imaging survey of a sample of isolated Herbig Ae-Be (HAeBe) stars aimed at searching for close companions. The fraction of wide binaries is found to be significantly higher in HAeBe stars than in solar-mass field dwarfs, and suggests a companion star fraction possibly larger than 1.

Orbits, masses and dynamical parallaxes of 12 visual binary systems [PDF]

open access: diamondSerbian Astronomical Journal, 2003
In this paper the preliminary orbital elements are presented for the following double stars: WDS 00153+4412 = A 1256 AB, WDS 00470+2315 = HU 413, WDS 00520+3154 = A 924, WDS 01036+6341 = MLR 87, WDS 01131+2942 = A 1260, WDS 01158+0947 = A 2102, WDS 01200-

On the component masses of visual binaries

open access: diamondSerbian Astronomical Journal, 2010
In the Sixth Catalog of Orbits of Visual Binary Stars we found those belonging to the Main Sequence to form a sample containing 432 visual binaries. Their total masses were obtained dynamically, i.e. they were calculated using the orbital elements and the new Hipparcos parallaxes.

Detecting New Visual Binaries in Gaia DR3 with Gaia and Two Micron All Sky Survey (2MASS) Photometry. I. New Candidate Binaries within 200 pc of the Sun

open access: yesThe Astronomical Journal, 2023
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

Statistical study of visual binaries [PDF]

open access: yesAstrophysical Bulletin, 2017
In this paper, some statistical distributions of wide pairs included in Double Star Catalogue are investigated. Frequency distributions and testing hypothesis are derived for some basic parameters of visual binaries. The results reached indicate that, it was found that the magnitude difference is distributed exponentially, which means that the majority
