Planetary Nebula Library: Hydro Runs
Reason for Library
Here we explore a variety possible parameters and environments that can shape planetary nebulae, presented in various forms. This library will record a number of combinations of different density backgrounds and types of flows and also any parameter changes within those different combinations. The environments and flow structures are listed below. Environments:
- Constant Ambient: The surrounding density is initially constant.
- Stratified Ambient: The surrounding density falls off as 1/r2.
- Toroidal Ambient: The surrounding density decays from the equator to the pole as defined in Frank & Mellema, 1994 Apj
Flow Structures:
- Clump: A spherical cloud of gas.
- Jet: A constant stream of gas.
- Diverging Wind: A constant stream of gas that sweeps an arc in the surrounding medium.
The tables below will be updated periodically with movies of new runs and their parameters with the newest runs appearing first.
Please see Ruka's PN Page for more movies and additional information.
| Update 9/04: Please note that the structure of the table has been changed. |

The following table shows different runs where changes made to the jet parameters are given in bold.
