• Expanding grid model for the formation of the Homunculus nebula, including radiative cooling.
• Fixed grid model for the formation of the Homunculus nebula, including radiative cooling. This zooms in on the innermost region near the equator, showing the interaction of the wind with the dense ring surrounding it, during the first few years of the interaction.

 Compare the above simulations to the ones below, where the gas was not allowed to cool.

• Expanding grid, showing the evolution of the pressure with time..

 
•  Fixed grid, zooming in on the central location
