List of books

[recommended, same book as the first semester]
1. The Physics of Fluids and Plasmas: An Introduction for Astrophysicists

[basic general astrophysics, old and good books, but a little bit hard to read]
2. Physics Of Astrophysics V1-Radiation
3. Hydrodynamic and Hydromagnetic Stability

[basic specific astrophysics with recent updates]
4. Introduction to Astrochemistry: Chemical Evolution from Interstellar Clouds to Star and Planet Formation
5. Introduction to Stellar Structure

Exercise

Make a density plot with your own plotting tool.
I made a set of density data. This is just a snapshot file. The three files contain the data of x axis, y axis, and the density.
The simulation uses Athena++.

[optional]
Make a movie of the simulation with this full data set. This contains VTK files. I recommend using VisIt for visualization. Follow the instruction of documentation of Athena++.
Here I put a movie that I made. But don't open this file before you make your own movie.

Exercise 2

Let us understand the hydrodynamical instabilities, which we have learned in Section 7, by using numerical simulations.
First, download and install Athena++ to your computer.
Then, perform 2d hydro simulation with the input file [athena/inputs/hydro/athinput.rt2d].
The questions are:
What is this instability?
What does happen if there is no perturbation? Try that by changing the input parameters.
Find the dispersion relation and perform two simulations where the instability occurs on one of them and not on the other setup.
