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 ...

Image and Video Tokenization with Binary Spherical Quantization
International Conference on Learning RepresentationsWe propose a new transformer-based image and video tokenizer with Binary Spherical Quantization (BSQ). BSQ projects the high-dimensional visual embedding to a lower-dimensional hypersphere and then applies binary quantization.

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.

The Orbit of a Visual Binary (L)
1969Our material is a reproduction of visual observations obtained by a number of observers in the 19th and 20th century. The brightest component F is always taken as the origin; for the fainter component B the observer has measured the distance to F and the direction of FB. We only consider the relative orbit.

Orbit of a Visual Binary System
2004A new method to solve the problem of initial orbit determination of any visual binary system is presented. The apparent orbit, which is the projection of the true orbit on the plane of sky, is expressed in a closed form as a function of the keplerian orbital elements by a suited choice of two angular parameters instead of inclination and argument of ...

The Orbital Elements of a Visual Binary
1978The 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 ...

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).
