摘要

在本文中,我们提出了2008年7月23日塔吉克斯坦超级流星的光度质量和密度的研究。利用卫星和地面观测的综合数据,通过三种方法计算质量:光度法(基于最大亮度高度的光强)、图形法(使用已公布的汽车数据)和超级火流星的动能。因此,质量的计算值分别为25.3、19.9和18.9吨(平均值为21.3±2.1吨)。采用阻力方程、最大光度高度和列车起点处的大气密度方程和标准pe对超固体密度进行了评价。三种方法计算得到的密度分别为1.1、0.53和0.95 g/cm3(其中超氧化物的平均密度为0.86±0.15 g/cm3)。

Physical properties of the superbolide of Tajikistan based on combined satellite and ground-based observations
In this paper we present the study of the photometric mass and density for the Tajikistan superbolide of 23 July 2008. Using the combined data from satellite and ground-based observations the mass was calculated by three approaches: photometric (based on the light intensity at the height of maximum brightness), graphics (using published data of cars) and using the kinetic energy of the superbolide. As a result, the calculated values of the mass are 25.3, 19.9 and 18.9 tons, respectively (with average value of 21.3 ± 2.1 tons). The superbolid density was evaluated using the drag equation, the equation density of atmosphere at the heights of the maximum luminosity and beginning of the train and criterion-PE. The densities calculated by these three methods are equal to 1.1, 0.53 and 0.95 g/cm3 (with the average superbolide density as 0.86 ± 0.15 g/cm3).
