论文摘要
我们介绍了轨道计算的结果，以支持Kreutz Sungrazer系统最近提出的接触二进制模型（Sekanina 2021，2022）。我们证明了Ikeya-seki（C/1965 S1）先前在1106年的彗星（X/1106 C1）之后经过数十年（X/1106 C1）之后的毛利lion，并认为，就像1882年9月的伟大彗星（C/1882 R1）一样，显然是11月113日Sungr的comet comet exply of the Comet的片段。 1843（C/1843 D1）。由于不涉及动量交换，因此证明，在围绕周附近潮汐分解的克雷兹日光浴者的碎片最终会在轨道上散发出明显不同的时期，因为它们的质量中心相对于父母的质量中心径向移动了几公里。由罗马历史学家录制的AD 363的日光彗星被安置在我们的计算中，这是克鲁兹避免祖先分手后的第一次出现。我们将1843-1106-363（Lobe I）和1882-1138-363（Lobe II）链接到单个非倾向轨道和重力返回的近日，并在碎片事件中获得了较小的质量转移。我们还成功地将亚里士多德彗星的运动建模为旋转祖细胞，该祖先在aphelion（在几m/s上）分别为两个裂片，分别是1843年和1882年的Sungrazers的前体。并提供1963-1041-363彗星Pereyra（C/1963 R1）的链接。物质疲劳可能会导致整个轨道（包括吞吐量）在整个轨道上的碎裂作用。 - 注意到轨道软件中的非掠夺法律的持续问题。
We present the results of our orbital computations in support of the recently proposed contact-binary model for the Kreutz sungrazer system (Sekanina 2021, 2022). We demonstrate that comet Ikeya-Seki (C/1965 S1) previously passed perihelion decades after the Great Comet of 1106 (X/1106 C1) and argue that, like the Great September Comet of 1882 (C/1882 R1), it evidently was a fragment of the comet recorded by the Chinese in September 1138. The 1106 sungrazer appears instead to have been the previous appearance of the Great March Comet of 1843 (C/1843 D1). With no momentum exchange involved, fragments of a Kreutz sungrazer breaking up tidally near perihelion are shown to end up in orbits with markedly different periods because their centers of mass are radially shifted by a few kilometers relative to the parent. The daylight comets of AD 363, recorded by a Roman historian, are accommodated in our computations as the first appearance of the Kreutz sungrazers after their bilobed progenitor's breakup. We link the 1843-1106-363 (Lobe I) and 1882-1138-363 (Lobe II) returns to perihelion by single nongravitational orbits and gravitationally with minor center-of-mass shifts acquired in fragmentation events. We also successfully model the motion of Aristotle's comet as the rotating progenitor that at aphelion split (at a few m/s) into the two lobes, the precursors of, respectively, the 1843 and 1882 sungrazers; and provide a 1963-1041-363 link for comet Pereyra (C/1963 R1). Material fatigue could contribute to sungrazers' fragmentation throughout the orbit, including aphelion. -- Continuing problems with the nongravitational law in orbit software are noted.
