Visual Binaries; Orbital Elements

1981
The 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).

The Orbital Elements of a Visual Binary

1978
The orbit of a visual pair describes, in the form of seven so-called orbital elements, the motion of the companion relative to the primary star, such as is obtained from the relative observations. In the two-body problem with the masses M1 and M2, the radius vector r, and the constant of gravitation k2, the relative motion is represented by the second ...

Variation of Geometric Orbital Elements

1989
The term variation of elements is not only applied to indicate that the elements of an orbit are affected by small additional forces applied to a satellite (in addition to the Kepler force) and consequently vary, but also indicates a method to determine these changes, which was introduced by Euler* in 1748.

(Two Line) Orbital Elements

1998
romanticism for data fanciers and ham radio fans, watching sunsets and satellite launches — staging and making perceptible the activities and patterns of motion of “invisible” forms of technology that seem to be capable of independent action. the user has the opportunity to follow the race of NOAA14 and meteor 3–5 — two earth observation satellites ...
