Title: Meteors and Celestial Dynamics 

Abstract: The area of celestial dynamics has been and is ripe with applications of contemporary mathematics. However there has been a distinct lack of formalism and applications of advanced methods in the more experimental areas of celestial dynamics, such as meteor science. Thus we have developed a skeleton version of a new toolbox for statistical small body dynamics in the Solar system. We will present the general idea and methods behind the software and its possible applications. The celestial dynamics are handled by standard Hamiltonian splitting methods and common ODE solvers. We also plan to implement stability analysis methods such as Lyapunov Indicators, Fast Lyapunov Indicators, and Mean Exponential Growth factor of Nearby Orbits using the same solvers. Currently, the software is constructed to generate clones of parent bodies drawn from multivariate probability distribution calculated from uncertainties in observational parameters by Bayesian inversion theory. As we then sample the initial distributions in a Monte-Carlo fashion we also examine convergence and find both scenario configurations and their respective probability. We have used this to examine the comet 21P/Giacobini-Zinner and its generated meteoroid streams that produce the meteor showers on Earth of the 1933, 1946, 2011, and 2012 October Draconids. 

Aim and Scope of the Series:

The goal of the series is to present some of the current research subjects at the Division of Mathematics. Most of the talks in this series are aimed at Engineers and Applied Scientists at LTU that may find the subjects interesting for their research projects and graduate programmes. 

The topic and level of a particular seminar depends on the speaker. Some speakers will provide a smooth introduction to their subject while others will concentrate more on recent research results or discuss open problems. Each seminar will be announced and scheduled well in advanced and the titles and abstracts of the talks will make it clear what the topic and level will be.

Who can Attend?

The seminars are open to all staff members and students at LTU from all divisions and departments, including PhD students, Post Docs and visiting scientists at LTU.

Who can give a Talk?

If you wish to give a talk in this series, you are very welcome to do so. In this case, please provide a short abstract and your motivation for your talk in this series and send it to We will then contact you with further details. 

List of Speakers (in alphabetical order): Per Bergström, Ove Edlund, Marianna Euler, Norbert Euler, John Fabricius, Adam Jonsson, Elena Miroshnikova, Natasha Samko, Thomas Strömberg, Inge Söderkvist, Peter Wall, and more.
