论文摘要
作者利用从公元前1404年至240公元前240年之间从彗星哈雷通道中弹出的颗粒的轨道整合,研究了可能在西半球观察到的Orionids可能爆发(Eta Aquariids的双淋浴)。在较早的轨道整合研究中,作者确定,ETA水族箱流星淋浴的可能爆发与Maya Classic时期的某些事件(AD 250-900)相关的可能性很高。此前的检查是可能在西半球记录的古代流星爆发中的第一次科学询问,那里以前没有哥伦比亚前观察。在当前的论文中,目的是描述经典玛雅铭文中记录的稀有但可能发生的Orionid爆发的轨道动力学。具体而言,在30个可能的目标年中,AD 417和585中发现了明显的爆发。在那两年中,爆发的驾驶机制是Jovian 1:6和1:7的平均运动共振,以维持Orionid流中的紧凑型结构以超过1 ky的速度。此外,中国记录的公元585年的Orionid爆发得到了证实。
Using orbital integrations of particles ejected from Comet Halley's passages between 1404 BC and 240 BC, the authors investigate possible outbursts of the Orionids (twin shower of the Eta Aquariids) that may have been observed in the western hemisphere. In an earlier orbital integration study the authors determined there was a high probability linking probable outbursts of the Eta Aquariid meteor shower with certain events recorded in inscriptions during the Maya Classic Period, AD 250-900. This prior examination was the first scientific inquiry of its kind into ancient meteor outbursts possibly recorded in the western hemisphere where previously no pre-Columbian observations had existed. In the current paper the aim is to describe orbital dynamics of rare but probable Orionid outbursts that would have occurred on or near applicable dates recorded in the Classic Maya inscriptions. Specifically, significant probable outbursts are found in AD 417 and 585 out of 30 possible target years. The driving mechanisms for outbursts in those two years are Jovian 1:6 and 1:7 mean motion resonances acting to maintain compact structures within the Orionid stream for over 1 kyr. Furthermore, an Orionid outburst in AD 585 recorded by China is confirmed.
