Day 2 Intro Slides (Part 2)
A reminder of what we have discovered so far: the importance of the time step! Lets think about conserved quantities...
Code
Plot Analytical + Numerical 2-Body Problem + Indexing Hints
Some python code for plotting an elliptical solution for the 2-Body problem from Day 1. Some hints for setting up indexing for each planet.
Resources
Some 2-Body Problem Notes
Some notes on the 2-Body problem from Massimo Ricotti's computational astrophysics class.
Notes on Integration in N-body
Some notes on general integration of N-Body problems from Massimo Ricotti's computational astrophysics class.
Integration of ODE's
Some notes on integration methods for ordinary differential equations from Massimo Ricotti's computational astrophysics class.
Indepth Discussion of Several Integrators
Goes over some pros/cons of different sorts of integrators. Hermite integrators are discussed in section 2.3.2.
