A computer model of the ablation and slowing down of a meteor, and the hydrodynamic and radiative expansion of the meteor train, together with the associated air chemistry
Abstract
This paper will describe a new computer model that explicitly treats the ablation and slowing down of a meteor entering the atmosphere, and the deposition of the kinetic energy of the ablated meteor material. This energy deposition results in immediate formation of a high-temperature radially expanding shock wave, modified by intense radiative energy transport. For selected cross-sectional cuts along the meteor trajectory we compute the approximately cylindrical radiative/hydrodynamic evolution of this structure, including its luminosity and the associated atmospheric chemistry.
