流星的发光效率估算-I。不确定性分析
Luminous Efficiency Estimates of Meteors -I. Uncertainty analysis
摘要:
流星的发光效率知之甚少,但对于确定流星体质量至关重要。我们提出了一个不确定性分析的发光效率所确定的经典烧蚀方程,并提出了一种可能的方法来确定发光效率的真实流星事件。我们发现,一个两项指数拟合模拟滞后数据是能够重现模拟发光效率相当不错。
英文摘要:
The luminous efficiency of meteors is poorly known, but critical for determining the meteoroid mass. We present an uncertainty analysis of the luminous efficiency as determined by the classical ablation equations, and suggest a possible method for determining the luminous efficiency of real meteor events. We find that a two-term exponential fit to simulated lag data is able to reproduce simulated luminous efficiencies reasonably well.
