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 of meteoroids ejected at different points of the comet orbit with the most likely
ejection velocities. The change of the D values is investigated depending on the dynamic evolution of the streams by integrating forward the orbital elements of the
model particles using the Cowell method taking into account the perturbations from all planets. It is shown that after ten
rotations, for Pons-Winneckids the upper limit of the D criterion is higher than 0.5 and for Perseids the D criterion does not exceed 0.2. 相似文献

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. Two-color diagrams for the brightness maxima are constructed. It is shown that meteors in the Perseid, Taurid, and Geminid showers form clusters in the two-color diagrams. Variations in color with a temporal resolution of 0.1 s are considered for some meteors.
