Advanced Labwork in Astronomy and Astrophysics

Summer Term 2019

The specialized course in Astronomy and Astrophysics offers an advanced labwork. The experiments will take place at section Astronomy (Sand 1) or at section Computational Physics (Auf der Morgenstelle 10).
In SS 2019 the labwork will be held as block during semester break from 29.07. - 09.08.2019 (Mo, We, Fr 9:00-18:00). If there should occur overlaps with other courses, single experiments might be shifted to later dates in agreement with the corresponding tutor. In the summer term 2019 the labwork will be held as block during semester break from 29.07. - 09.08.2019 (Mo, We, Fr 9:00-18:00) Preparatory meeting: Tu. 23.07.2019, 9:00 Uhr, Astronomy, Sand 1, lecture hall room A 104.

The students have to choose one of the following two exercises:


I --- Chaos in planetary systems - Wilhelm Kley & Christoph Schäfer
In this part of the practical course, the students will develop a computer code for the simulation of the gravitational interaction between planets and will validate their code with the two body problem. After successfully simulating the two body problem, the students will apply their code to the chaotic three body problem. Students are expected to read the instructions.

Instructions and related paper

• Versuchsanleitung (english version).
• Dynamics of Systems of two close Planets, paper by Brett Gladman. The author illustrates the basics for the chaotic three body system. One part of the practical course is related to this paper.

II --- N-Body Simulations with REBOUND - Christoph Schäfer
In this part of the practical course, the students will use an existing N-Body software package to address several problems such as the stability of Saturn's rings and the Kirkwood gaps. Students are expected to read the instructions.

Instructions

• Versuchsanleitung (english version).
