Planetary Nebula Library: Hydro Runs

Update 10/14:

10,000K Jet traveling at 800km/s
On the left is a model with cooling and on the right is a model without cooling. Both are at time = 577.5 years.

Reason for Library

Here we explore a variety of 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. (Go to the Clump + Jet page for models that include both a clump and jet.)

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 by the following variables:
    • describes the contrast in density of the torus from the pole to the equator.
    • describes how elliptical or spherical the torus is. Small values coincide with a more elliptical torus while values closer to 1 indicate a more spherical torus.

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.

Below are the standard parameters used in each run. Any changes to these parameters will be noted in the table preceding the image table.

Jet Density 40,000 cm-3
Jet Temperature 10 K
