Statistical study of visual binaries
Astrophysics and Space Science, 1988A statistical study of physical pairs from IDS catalogue has been performed. For 2811 binaries with luminosity class V primaries it has been found that their mass function is a Salpeter one; their distribution over semi-major axes of orbits is dN ∝ d log a. The rate of duplicity of stars is close to 1.

The visual binary Lambda Ophiuchi
Publications of the Astronomical Society of the Pacific, 1993The orbital elements of this visual binary are revised; we find a=0.91" and P=129 yr. The mass ratio measured from a 75-yr series of astrometric plates supports the spectroscopically suspected presence of a third body.

Vistas in Astronomy, 1956
Abstract The results of some 130 years of double star discovery and measurement are briefly reviewed. Knowledge of stellar masses is perhaps the most important of these results; this in turn gave rise to dynamical parallaxes. As shown by statistics of the near neighbourhood of the Su, binaries, and even multiple stars, are by no means exceptional ...

Binary search tree visualization algorithm
2009 16th International Conference on Industrial Engineering and Engineering Management, 2009Binary search tree is a very common data structure in computer programming. Working with large BSTs can become complicated and inefficient unless a programmer can visualize them. This article contributes with two BST visualization algorithms that draw a tree in time linearly proportional to the number of nodes in a tree.

Visual Binaries in Planetary Nebulae
Publications of the Astronomical Society of the Pacific, 1973Close companions to the central stars have been observed in several planetary nebulae. Proper motions for some of these are consistent with physical association.

Visual Binaries; Orbital Elements
1981The present author’s earlier astrometric treatise (1967) contains a chapter on visual binaries, which is repeated here with minor changes. We shall be primarily interested in the orbital effects of visual binaries on the paths of the components as measured on a background of reference stars (Chapters 1 Iff).

Binary Mesh Partitioning for Cache-Efficient Visualization
IEEE Transactions on Visualization and Computer Graphics, 2010One important bottleneck when visualizing large data sets is the data transfer between processor and memory. Cache-aware (CA) and cache-oblivious (CO) algorithms take into consideration the memory hierarchy to design cache efficient algorithms. CO approaches have the advantage to adapt to unknown and varying memory hierarchies.

Flare Activity of Visual Binary COU 14
Astrophysics and Space Science, 1998Two flares with an amplitude of more than 0m.3 each in B and V colours and another four with less amplitude in U band were detected during photometric and polarimetric monitoring of the nearby visual binary COU14. Irregular long term brightness and colour variations were registered while no significant polarization signal was detected.
