NUMERICAL SIMULATION OF MATERIAL EJECTION INTO THE ATMOSPHERE INDUCED BY OBLIQUE IMPACTS OF TEN-KILOMETER- DIAMETER COMETS INTO THE OCEAN

Abstract

The results of three-dimensional numerical modeling of the oblique impacts of ten-kilometer water comets with velocities of 20 to 50 km/s at an angle of 45° onto a solid surface and into an ocean up to 6 km deep are presented. The maximum masses of ocean water, comet and soil matter ejected into the atmosphere, as well as the masses of water, impactor and soil matter remaining in the atmosphere 10 minutes after the impact are calculated. The mass of vaporized ejecta is determined.
