An important fundamental problem is to find periodic components (if they exist) in distributions of elements of orbits of comets, asteroids and meteor showers. The method of superposed epochs is a non-parametric method of finding of hidden periodicity and is based on building of series' phase diagrams for different values of test periods. Its advantage is the absence of a priori assumptions about...
There are theories which state that a space of possible orbits in gravitational systems of planetary type is discrete, so there are systems of stable and unstable orbits. A discrete structure of gravitational systems of planetary type should be evident in distributions of orbital energy, angular momentum and some elements of orbits. The easiest way to test such theories is to look for harmonic components...
In this paper the scientific achievements and historical facts are briefly outlined. A good deal of work was carried out by Kharkiv (Ukraine) researches under the guidance of Prof. B. L. Kashcheyev who had a made a truly tangible contribution to meteor astronomy. This research team had succeeded in gathering ample evidence on meteor exploration, especially when using the so-called radar method that...
