车里雅宾斯克和通古斯卡流星体的精化参数及其爆发模式
Refined Parameters of Chelyabinsk and Tunguska Meteoroids and their Explosion Modes
摘要:
本文介绍了数学模型的应用,该模型建立了天体在太阳和地球活动范围内的运动参数与这些物体的质量-能量特性及其在地球大气层中破坏时的爆炸模式之间的关系,而这种关系又与在下垫面观察到的现象相联系。该模型被用于计算造成车里雅宾斯克和通古斯爆炸的物体的特征,并使用了最近的科学出版物(2013年底至2014年初)中描述的轨道参数。原来车里雅宾斯克流星体的大小等于180 - 185米,质量接近1.8兆吨。它的爆炸能量相当于57兆吨TNT,通古斯卡流星体的大小相当于105米,质量为0.35兆吨,而爆炸能量约为14.5兆吨TNT。由于这两个天体的共同起源,它们的平均密度相等--约为570 kg/m^3。
英文摘要:
This paper describes application of mathematical model that establishes relationship between parameters of celestial bodies motion in the spheres of activity of the Sun and the Earth with mass-energy characteristics of these objects and their explosion modes during destruction in the Earth atmosphere, that in turn are linked with phenomena observed on underlying surface. This model was used to calculate the characteristics of objects that caused the Chelyabinsk and Tunguska explosions with using of its trajectory parameters described in recent scientific publications (late 2013 - early 2014). It turned out that the size of Chelyabinsk meteoroid was equal to 180 - 185 meters, and its mass was close to 1.8 megatons. Energy of its explosion was equal to 57 megatons of TNT, size of Tunguska meteoroid was equal to 105 m, mass - 0.35 megatons, while energy of explosion was about of 14.5 megatons of TNT. Due to the common origin of these two celestial bodies their average density was equal - about of 570 kg/m^3.
