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 9/02: Images have been added for the jet with a velocity of 200 km/s of the thermal pressure and for a jet with a velocity of 300 km/s of density and thermal pressure. Movie for each of these are currently being created.

A list of all changes made to this page can be found ​here.
