    Groups of meteorite-producing meteoroids and meteorites in asteroidal orbits and their sources
    (Одеський національний університет імені І. І. Мечникова, 2020) Gorbanev, Yu. M.; Konovalova, N. A.; Davruqov, N. Kh.
    This paper presents the results of the analysis of possible existence of nine near-Earth meteorite-producing groups in asteroidal orbits, consisting of sporadic fireballs from the IAU MDC 2007 database, sporadic meteors from the SonotaCo database, meteorites - namely, L5, L6 and H4-H6 ordinary chondrites and an ureilite, for which atmospheric and orbital parameters are known from instrumental observations - and their plausible parent bodies, that is, near-Earth asteroids (NEAs). Orbits of the selected members of meteoriteproducing groups were classified as asteroidal according to the Tisserand parameter TJ > 3.1. In order to test the link between meteorite-producing groups in asteroidal orbits and their plausible parent bodies, we carried out an investigation into the possible existence of some known NEAs that move in similar orbits. Based on the orbital similarity, determined using the Drummond (Dd) and Southworth & Hawkins (Dsh) orbital similarity criteria, some associations between the identified NEAs, known meteorites in asteroidal orbits and small, as well as meteorite-dropping, meteoroids have been suggested. As a result, several meteorite-dropping sporadic fireballs and small meteors, whose orbits are currently similar to the orbits of known meteorites, have been detected and reckoned as possible members of the groups in asteroidal orbits; their plausible source regions have also been considered.

    Groups of meteorites and meteorite-dropping fireballs in asteroidal orbits
    (2021) Gorbanev, Yuriy M.; Konovalova, N. A.; Davruqov, N. Kh.; Горбаньов, Юрій Михайлович; Горбанёв, Юрий Михайлович
    This paper presents the results of a study of the existence of nine near-Earth meteorite-producing groups in asteroidal orbits, containing sporadic reballs from the IAU MDC-2007 database, sporadic meteors from the SonotaCo database, meteorites namely, L5, L6 and H4−H6 ordinary chondrites and an ureilite, for which atmospheric and orbital parameters are known from instrumental observations. Orbits of the selected members of meteorite-producing groups were classi ed as asteroid orbits according to the Tisserand parameter Tj > 3.1. Dynamic links between the members of the identi ed meteorite-producing groups and instrumentally observed known meteorites which were taken as a reference for the search of potential group members were tested using orbital similarity criteria, in particular the Drummond criterion DD and the Southworth and Hawkins criterion DSH. As a result, several meteorite-dropping sporadic reballs and small meteors, whose orbits are similar to the asteroid orbits of nine known meteorites, were detected and reckoned as possible members of meteorite-producing groups.

    On the annual occurrence of large and small sporadic meteoroids and meteorites
    (2019) Konovalova, N. A.; Gorbanev, Yuriy M.; Davruqov, N. Kh.; Горбаньов, Юрій Михайлович; Горбанёв, Юрий Михайлович
    The observations of the meteors and bright fireballs by meteor stations and fireball networks allows to get the more precise data on atmospheric trajectories and heliocentric orbits of this bodies. In recent years, several works were published on the subjects of the annual occurrence of fireballs. On the base of the Millman Fireball Archive the time of occurrence data for 2373 fireball events observed from across Canada was studied Beech [1]. An analysis of the frequency of the superfireballs based on the reports which appeared in newspapers in the last 150 years was made in [2]. Shrbeny et al. [3] studied the fireball activity from the Desert Fireball Network records from 2006 to 2014 and identified several time periods with increased number of fireballs. We present here the results of the analysis of annual occurrence of large and small sporadic meteoroids and meteorites with known fall data.
