摘要：

我总结和精简的轨道演化和级联的克鲁兹掠日天体的碎片最近的建模结果。该模型从亚里士多德的彗星开始-其核心被假定为接触双星的祖先-在远日点附近分裂成两个裂片，最后以SOHO矮天体作为分裂过程的最终产物。1843年的大三月彗星（Great March Comet）是星族I的成员，1882年的大九月彗星（Great September Comet）是星族II的成员，被认为是现存质量最大的两颗彗星。我确定，克鲁兹星系目前由9个星群组成，其中之一--与佩雷拉彗星有关--是星群I的一个分支。作为新模型的一部分，克罗伊茨系统的补充是公元363年的日光彗星，由罗马历史学家阿米亚努斯·马塞利努斯记录，以及1041年9月和1138年9月的中国彗星，两者都在何的目录中列出。363年的彗星是第一代碎片，后者--连同1106年的大彗星--是第二代碎片。注意力是针对人口的近日点距离的SOHO掠日者的直方图和这个距离作为一个功能的上升交点的经度的绘图。在未来几十年内，明亮的裸眼克鲁兹掠日者的到来被预测。

英文摘要：

I summarize and streamline the results of recent modeling of the orbital evolution and cascading fragmentation of the Kreutz sungrazers. The model starts with Aristotle's comet -- the progenitor whose nucleus is assumed to be a contact binary -- splitting near aphelion into the two lobes and concludes with the SOHO dwarf objects as the end products of the fragmentation process. The Great March Comet of 1843, a member of Population I, and the Great September Comet of 1882, a member of Population II, are deemed the largest surviving masses of the lobes. I establish that the Kreutz system consists currently of nine populations, one of which -- associated with comet Pereyra -- is a side branch of Population I. The additions to the Kreutz system proposed as part of the new model are the daylight comets of AD 363, recorded by the Roman historian Ammianus Marcellinus, and the Chinese comets of September 1041 and September 1138, both listed in Ho's catalogue. The comets of 363 are the first-generation fragments, the latter -- together with the Great Comet of 1106 -- the second-generation fragments. Attention is directed toward the populations' histograms of perihelion distance of the SOHO sungrazers and the plots of this distance as a function of the longitude of the ascending node. Arrival of bright, naked-eye Kreutz sungrazers in the coming decades is predicted.
