论文摘要
在1995年5月在2022年5月的1995年爆发期间产生的73p/schmassmann-Wachmann〜3的流星材料的相遇提供了一个罕见而宝贵的机会，可以理解碎片彗星。在这里，我们探讨了各种射血构型及其对在5月31日UT 2022凌晨检测到的流星爆发的影响。我们表明，灰尘必须比水冰升华模型所计算的$ \ sim4 $至$ 5 \ $ \ $ \ times $快，以使观察到的流星活动匹配。由于只有一小部分具有狭窄横截面范围的颗粒已经到达地球，因此流星亮度的较大传播可能表明步道中存在大而多孔的流星体。其他效果，例如增强的月球钠尾部和在遭遇期间也可能发生了流星径的可见光。
The encounter of the meteoric material from 73P/Schmassmann--Wachmann~3 produced during the comet's 1995 outburst in May 2022 provides a rare and valuable opportunity to understand a fragmenting comet. Here we explore various ejection configurations and their impact on the meteor outburst detected in the early hours of UT 2022 May 31. We show that the dust must have been ejected $\sim4$ to $5\times$ faster than calculated by water-ice sublimation model to best match the observed meteor activity. As only a small subset of particles with a narrow range of cross-section is expected to have reached the Earth, the large spread of meteor brightness likely indicates the presence of large but porous meteoroids in the trail. Other effects such as an enhanced lunar sodium tail and a visible glow from the meteoroid trail may have also occurred during the encounter.
