PNe Production Runs

A quick glance at the four models — density evolution

panels are not time synchronized

  • Top left: Model 1, non-cooling, high-momentum
  • Top right: Model 2, non-cooling, low-momentum
  • Bottom left: Model 3, DM-cooling, high-momentum
  • Bottom right: Model 4, DM-cooling, low-momentum (notice the scaling difference)

Some take-away points

  1. Outflow is highly supersonic, and creates layers of shock.

​Example: Mach number in model 1

  1. Outflow is highly collimated. Most of the outflow materials are redirected into the top and bottom lobes.

​Example: Outflow tracer and mesh in model 3

  1. Top-bottom asymmetry is most dramatically shown in model 4, see the bottom right panel above (or click to show in full-screen).

Table of index

Model # Description Last frame # Days of outflow Movies Frames
1 Non-cooling, High-momentum 210 1200 ​movies ​frames
2 Non-cooling, Low-momentum 259 2180 ​movies ​frames
3 DM-Cooling, High-momentum 223 1460 ​movies ​frames
4 DM-Cooling, Low-momentum 300 3000 ​movies ​frames

Naming rule decoded:

  • "ADB" = "adiabatic", no extra cooling in the code
  • "DMC" = "DM-cooling", cooling curve applied to T > 30000 K
  • "_High"/"_Low" = "high-momentum outflow" or "low-momentum outflow"
  • For each model, I plotted the following variables:
    1. Mach number with contours for selected Mach number
    2. Mesh and outflow tracer density
    3. Temperature and contour at 10000 K
    4. Density, labeled as "rho"
    5. Density at the orbital disk, labeled as "zrho"
  • Numerals indicate certain zoom-in options:
    1. the entire simulation domain
    2. core area, focused on the CEE ejecta
    3. center, slightly zoomed out from the core
    4. lobes in the early stage
    5. tall, extended lobes in later stage
