DAY 1
Lecture Notes

Day 1 Lecture Slides
All of the notes from the intro of day 1. This includes intro to computational astrophysics, overview of N-body motion and the specific application of 2-Body motion (both analytically and computationally).
Code

Plot Analytical 2-Body Problem
Some python code for plotting an elliptical solution for the 2-Body problem.

Plot Analytical + Numerical 2-Body Problem
Some python code for plotting an elliptical solution for the 2-Body problem. This includes the analytical solution and some sudo-code for setting up numerical integration with a Euler's-type integration scheme.
