Analysis of orbital theories for the construction of the numerical theory of the lunar physical librations

Zagidullin A.; Petrova N.; Usanin V.; Andreev A.; Nefedyev Y. (2018)

© Published under licence by IOP Publishing Ltd. When using the numerical approach to construct the theory of physical libration of the Moon, it is necessary to solve the problem of comparing the numerical and analytical ...
Analysis of the upper limit of the Southworth-hawkins d criterion for the Pons-winneckid and perseid meteoroid streams

Ishmukhametova M.; Kondrat'eva E.; Usanin V. (2009)

The value of the upper limit of the Southworth-Hawkins D criterion for the Pons-Winneckids (June Bootid) and Perseids meteor streams is analyzed on the basis of the comparison of the parent comet orbit with the model orbits ...
Characteristic Features of the Colors of Shower Meteors and Sporadic Meteors from Observations with the Mini-MegaTORTORA System

Usanin V.; Nefedyev Y.; Sokolova M. (2019)

© 2019, Pleiades Publishing, Ltd. Results of BV R observations of meteors in the Perseid, Taurid, Orionid, Geminid, and Lyrid showers, as well as sporadic meteors, carried out with the Mini-MegaTORTORA system are presented. ...
Parameters of numerical and analytical ephemerides of the moon use complex systems analysis methods

Zagidullin A.; Usanin V.; Petrova N.; Nefedyev Y.; Andreev A. (2020)

Copyright © SGEM WORLD SCIENCE (SWS) Society 2020. This work considers the study of libration dynamics of the planets' moons. To analysis such processes, it is necessary to use methods for investigating complex systems, ...
Use of long-term models for analysis of comet Encke's motion

Usanin V.; Nefedyev Y.; Andreev A. (2016)

© 2016 COSPARThis paper is focused on the problem of the reactive non-gravitational effects change in the cometary motion caused by the comet's activity fading. The modern researches have been reviewed. The necessity of a ...
Use of long-term nongravitational force models for fitting astrometric observations of comet Encke

Usanin V.; Nefedyev Y.; Andreev A. (2017)

© 2017 COSPAR Based on the equations derived in (Usanin et al., 2016) a new solution combining the observations of 30 apparitions of the comet Encke from 1911 to 2010 is obtained. For the first time in the worldwide practice ...
