Mathematical Modelling of Meteoroid Streams, 1st ed. 2020 SpringerBriefs in Astronomy Series

Couverture de l’ouvrage Mathematical Modelling of Meteoroid Streams

Modern computer power and high-precision observational data have greatly improved the reliability of meteoroid stream models. At present, scientific research calls for two kinds of models: precise ones for individual streams, and statistically averaged ones for Solar System dust distribution models. Thus, there is a wide field of study open to stream modellers.

This brief describes step-by-step computer simulations of meteoroid stream formation and evolution. Detailed derivations of relevant formulae are given, along with plenty of helpful, digestible figures explaining the subtleties of the method. Each theoretical section ends with examples aimed to help readers practice and master the material.

Most of the examples are based on the Geminid meteoroid stream model, which has been developed by the author in the last 30 years. The book is intended for researchers interested in meteor astronomy and mathematical modelling, and it is also accessible to physics and astrophysics students.

Galina Ryabova is a Principal Researcher and Professor at Tomsk State University. Her scientific interests are mathematical modelling of meteoroid streams and interrelations in asteroid-comet-meteoroid complex. She developed a mathematical model of the Geminid meteoroid stream — one of the three existing stream models. She has served on the Organizing Committee of the International Astronomical Union's "Meteors, Meteorites and Interplanetary Dust" Commission (IAU C.F1). She was also a Council member of the International Meteor Organization. She is editor-in-chief of the reference book “Meteoroids: Sources of Meteors on the Earth and Beyond” (Cambridge University Press, 2019).

A detailed guide to computer modelling for the formation and evolution of meteoroid streams

Explains the practical subtleties of the method, which are not found in available scientific literature

Intended for individual research work, but can also be used for one-semester courses on mathematical modelling in physics
