Welcome!

The Illinois Astrophysical Dynamics Demonstrations (iADD) let you explore the behavior of gas, stars, and dark matter in a variety of astronomical environments using computer simulations. You can explore a range of phenomena at a level that\'s comfortable for you:

• For everyone: watch movies and read how planets, stars, black holes, and galaxies evolve
• For adventurers: take control of the wheel and run your own simulations
• For instructors: use iADD laboratory exercises in your course
• For developers: develop new simulations for iADD

To get started, choose a topic from one of the menus above.
