2012年和2013年英仙座流星雨期间探测到的月球撞击闪光分析
Analysis of Moon impact flashes detected during the 2012 and 2013 Perseids
摘要：
我们提出了我们的月球撞击闪光探测活动的英仙座流星雨在2012年和2013年的最大活动期间进行的结果。由于非常不利的几何条件，2012年只探测到英仙座流星体产生的一次闪光，但2013年确认了其中12次。闪光的视觉强度在6.6到9.3之间。据估计，来自这条流的流星体的发光效率为1.8 $\times$ 10 $^{-3}$。根据这一数值，撞击器质量将在1.9至190 g之间。此外，我们提出了一个标准，从统计的角度来看，可能的起源记录在月球表面的冲击闪光。
英文摘要：
We present the results of our Moon impact flashes detection campaigns performed around the maximum activity period of the Perseid meteor shower in 2012 and 2013. Just one flash produced by a Perseid meteoroid was detected in 2012 because of very unfavourable geometric conditions, but 12 of these were confirmed in 2013. The visual magnitude of the flashes ranged between 6.6 and 9.3. A luminous efficiency of 1.8 $\times$ 10$^{-3}$ has been estimated for meteoroids from this stream. According to this value, impactor masses would range between 1.9 and 190 g. In addition, we propose a criterion to establish, from a statistical point of view, the likely origin of impact flashes recorded on the lunar surface.
