A MODEL OF SINGLE AND FRAGMENTING METEOROID INTERACTION WITH ISOTHERMAL AND NON-ISOTHERMAL ATMOSPHERE

摘要

The basic equations of physical theory of meteors are considered without the assumption of atmospheric isothermality. Analytical solutions are found in the case of single and fragmenting meteoroids, the fragmentation process being modeled in terms of the statistical theory of strength (Weibull, 1939). The comparison against a classical solution is made for the single body model. The comparisons against the observations and gross-fragmentation model results are made for a fragmenting meteoroid. An example of parametric investigations based on the obtained solutions is provided.
