Creation of a system of genetic relationships between meteor showers and\u00a0their parent bodies using a multi-parameter model of near-Earth\u00a0celestial objects\u00a0(according to the results of the Ph.D. thesis)<\/div>\n
Abstract<\/strong><\/div>\n
\n
Currently, the registry of the International Astronomical Union (IAU)\u00a0contains information on 110 meteor showers confirmed by observations, 78 of\u00a0them are orphan showers with unfound parent bodies (PBs), mostly small meteor\u00a0showers with low activity, which complicates their observation and research. Thus,<\/div>\n
the study of the entire complex of MNTs and the establishment of their genetic\u00a0relationships is very important.<\/div>\n
To identify the meteor shower from PB, a synthetic method was developed,\u00a0which includes a set of criteria for the similarity of orbits and dynamic criteria,\u00a0which are a consequence of solving the restricted three-body problem.\u00a0When studying MNT bonds, there is a problem in the form of the lack of a\u00a0unified method for finding the threshold values of the criteria relative to which the\u00a0proximity of the orbits of bound MNTs is determined. In this paper, to solve this\u00a0problem, an algorithm for finding threshold values for each of the criteria included\u00a0in the synthetic method was developed and applied. There is also the problem of\u00a0selecting identified objects. As part of solving this problem, an independent\u00a0method for selecting candidates for PB was developed and applied for the selection\u00a0of related NEAs.<\/div>\n
The created synthetic method was applied to analyze the relationships\u00a0between the small meteor complexes \u03b4-Cancrids, \u03ba-Cygnids, h-Virginids,\u00a0Andromedids, and \u03c1-Geminids with the NEA of the Apollo and Amor groups. For\u00a0the selection of related NEAs, an independent method for selecting candidates for<\/div>\n
the PB was developed and applied. To check the reliability of the selected NEAs,\u00a0their relationships were assessed on the basis of the independent Southworth-Hawkins DSH criteria and its modification, the Asher DAH criterion.<\/div>\n
The structure of meteor showers has been studied – the distribution by mass\u00a0and the nature of the change in the luminosity function along the Earth’s orbit, the\u00a0radiants have been determined, and the distribution of the orbital elements of the\u00a0meteor showers has been analyzed.<\/div>\n
The results for the identified NEAs showed good agreement with the\u00a0probable PBs previously obtained by other authors for these meteor complexes.<\/div>\n
Based on the results of the work, 17 articles were published in the journals of the\u00a0SCOPUS and WoS citation system and 19 oral presentations were made at All-Russian and International conferences.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
