古玛雅人可能观测到的极有可能但罕见的猎户座爆发的轨道动力学
Orbital dynamics of highly probable but rare Orionid outbursts possibly observed by the ancient Maya
摘要：
利用哈雷彗星在公元前1404年至公元前240年之间的通道中喷射出的粒子的轨道积分，作者研究了可能在西半球观察到的猎户座流星雨（Eta宝瓶座流星雨的孪生流星雨）的可能爆发。在早期的轨道整合研究中，作者们确定，宝瓶座Eta流星雨的爆发与玛雅古典时期（公元250-900年）铭文中记录的某些事件有很高的可能性。这一先前的检查是对可能在西半球记录的古代流星爆发的第一次科学调查，在西半球以前没有哥伦布发现美洲大陆之前的观测。在目前的文件中，目的是描述罕见的，但可能的猎户座爆发，将发生在或接近适用的日期记录在经典玛雅铭文的轨道动力学。具体来说，在30个可能的目标年中，在公元417年和585年发现了显著的可能爆发。在这两年爆发的驱动机制是木星1：6和1：7平均运动共振作用，以维持猎户座流内的紧凑结构超过1 kyr。此外，还证实了我国记录的公元585年的一次猎户座流星雨爆发。
英文摘要：
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.
