Modelling the Entry of Meteoroids

Popis výsledku v původním jazyce

Meteoroids are most easily studied using the atmosphere as a detector. Under the right conditions, the passage of the meteoroid through the atmosphere may result in a meteorite falling to Earth or even the formation of an impact crater, but in most cases only the luminosity and ionization are available for analysis. Therefore, meteoroid properties (physical, chemical and all other possible properties) need to be determined through observations. The most obvious way to evaluate meteoroid properties is to apply a model to fit the observational data. Due to the variety of physical conditions that occur during the entry of meteoroids into the atmosphere, modelling efforts require the use of a wide range of different models- from sputtering of the surface under direct impacts of particles up to high-fidelity gasdynamical modelling. When starting to analyze observational data or to describe any physical phenomenon connected with meteors and bolides, one needs to understand clearly in what conditions this phenomenon is occurring and what physical processes need to be taken into account. This chapter reviews current entry models and discusses their boundaries and limitations.
