DETERMINATION OF PARAMETERS OF SMALL METEOROID BODIES: THE INFLUENCE OF THE HEAT OF ABLATION

Abstract

The ablation model is used to estimate the physical parameters of millimeter-sized meteoroids. In the ablation model used, the energy of the incident flow is spent only on the loss of mass of the meteoroid. The selection of parameters (size and density) of meteoroids for the reproduction of light curves is carried out using an automated approach. The influence of ablation heat on the mass, density and size of meteoroids was investigated. The estimates of meteoroid parameters obtained within the framework of this model are compared with estimates based on empirical relationships and with estimates based on another ablation model.
