Orbital Elements of visual binary stars with very short arcs: With application to double stars from the 1829 southern double star catalog of James Dunlop [PDF]

open access: yesAstronomische Nachrichten, 2022
Binary double stars are those whose binding energies are less than zero. Obtaining binary star orbits from short arcs has been a long-standing problem in astrophysics.

Orbits of 11 visual binary stars

New Astronomy, 2008
Abstract In this paper, the orbital elements for 11 visual binaries are given and calculated. Eight already possess orbits, but here they are recalculated. The reason is that recent measurements show higher residuals with respect to the corresponding ephemerides calculated by using the orbital elements given in the Sixth Catalog of Orbits of Visual ...

Precise radial velocity measurements of visual binary stars

Astrophysics and Space Science, 1988
The radial Velocity of a selected number of components of visual binaries have been measured. Attention is paid to systems suspected to have third (invisible) companions. A second aim of observation are selected couples from the “Catalog of radial velocities of binary stars” by Dommanget, for which the decision between different orbits is possible by ...

Statistics of Young Visual Binary Stars: Implications for (Binary) Star Formation

1997
It is well known that most main sequence stars are members of binary and multiple systems (e.g. Abt 1983, Herczeg 1984). Recent survey work in nearby star forming regions (such as Taurus and Ophiuchus) has demonstrated that this is also the case for young low-mass pre-main-sequence stars (Zinnecker, Brandner, Reipurth 1992; Reipurth and Zinnecker 1993,

Liminosity distribution function for visual binary stars

Astrophysics and Space Science, 1985
The ‘cosmic scatter’ of 147 of the best known visual binary stars on the Main Sequence is discussed and a new estimation of the luminosity distribution function for multiple star systems is presented. As long as the mass ratio q of a close binary is not smaller than 0.5, the distribution of close binary components is identical to the van Rhijn ...
