Relative motions of fragments of the split comets. I - A new approach

摘要: Abstract A new approach is formulated for the study of motions split comets. It based on assumption that two fragments a comet separate at rate determined primarily by slight difference between their effective solar attractions rather than impulse imparted them time splitting. The net dynamical effect interpreted as due to differential nongravitational forces, which depend size, density, structure, composition, and spin fragments. Since least smaller distances from Sun these forces vary inversely roughly square heliocentric distance, resembles radiation pressure, so formalism developed motion dust particle in cometary tail applicable principle. calculations show this provides reasonably good excellent fits observed separations great majority comets, it fails only case Comet 1957 VI. correlation endurance fragment investigated terms physical behavior fragments, with emphasis short-lived objects. Some unusual phenomena accompanying comets are discussed, comments also offered sequence splitting multiple nuclei distribution points space.
