Abstract

The Virginid meteoroid streams produce a series of meteor showers active annually during February–May. A certain parent comet is not found but a related association of some showers with near-Earth asteroids was previously established and a cometary origin of these asteroids was suggested. We performed a new search for NEAs belonging to the Virginid asteroid–meteoroid complex. On the base of calculation of orbital evolution of a sample of NEAs and determination of theoretical features of related showers a search for observable active showers close to theoretically predicted ones was carried out. As a result, the predicted showers of 27 NEAs were identified with the showers of the Virginid complex. Revealed association points to a cometary nature of NEAs that are moving within the stream and may be considered as extinct fragments of a larger comet-progenitor of the Virginid asteroid–meteoroid complex.

与处女星群有关的彗星源近地小行星

处女座流星群产生了一系列流星雨，每年 2 月至 5 月期间非常活跃。目前还没有发现其母体彗星，但以前曾证实一些流星雨与近地小行星有关，并认为这些小行星起源于彗星。我们对属于处女座小行星-流星体复合体的近地小行星进行了新的搜索。在计算近地小行星样本的轨道演变和确定相关阵雨的理论特征的基础上，我们对接近理论预测的可观测活动阵雨进行了搜索。结果，27 个近地天体的预测阵雨与处女星群的阵雨相吻合。所揭示的联系表明，在流内运动的近地小行星具有彗星性质，可将其视为维京里德小行星-流星体复合体的较大彗星-原生体的消亡碎片。
