Kolomiyets S. The structure of the meteor complex of high eccentric orbits of the Solar system on the results of the radar sensing of the atmosphere in Kharkiv

The thesis presents the solution of the actual scientific problem as to the structure of a meteor orbital complex with large eccentricities near the unit. The main result is that the research of the following areas was done: the structure of an insufficiently explored complex of high eccentric orbits of meteor-oids; the peculiarities of the distribution parameters of the orbit on the basis of experimental data of radar sensing of atmosphere in Kharkiv. The algorithm for calculating the uncertainty of the parameters of the orbital motion of meteoroids was created. We revised our estimations and found out that about 30% of the studied hyperbolic orbits of meteoroids cannot be explained by errors. Such orbits can be considered as real ones (0.8% of the total number of orbits). The mechanisms of formation of these orbits were presented. Some models of the complex are presented. We have dis-cussed the structure of meteor showers of the Halley comet and Eccentrids.
