The following 3D models show the morphologies of the elements in the core-collapse supernova simulations, 1 year after the explosion. The models are visualized using Three.js and are interactive. You can rotate, zoom, and pan the models using your mouse or trackpad.
They show the isosurfaces at 10% of the maximum density for C12, O16, Si28, and 56Ni + 56Co + 56Fe (called simply "56Ni" for short). I used Okabe-Ito colour palette in order to have something colorblind friendly.
The maximum density is computed integrating the density distribution of each element over the 4% most massive part of the ejecta. Doing so will allow us to avoid considering a very small percentage of mass when taking the maximum density. The values of the maximum density computed as such are given in the tables for each class.
