Effects of bolide parameters on the motion and destruction in the Earth's atmosphere

摘要

The present work describes numerical studies of movement and destruction of four meteoroids in the Earth's atmosphere: the Sikhote-Alin(1947),the Beneshov(1991),the Kunya-Urgench(1998)and the Chelyabinsk(2013)ones,which differ considerably in their dimensions,material properties,and trajectory parameters.The meteoroid mass loss due to radiation and thermal effects,and fragmentation of bodies during the motion along their trajectories is considered.These meteorites were chosen for the verification of newly developed models and to illustrate the impact of their parameters on the processes of movement and destruction.
