Illustration of the different ECSN modes observed in our parameter study. Each row shows a separate simulation, with each column representing various characteristic times. In each plot, the top half indicates Y_e and the bottom half ⟨A⟩ (note the varying limits in the color bars). Here, we also show contours of uniform log ρ (g cm⁻³). We note that in the last timestep of rho10.4_r73, we no longer fully trust the results of the simulation (e.g., the reappearance of heavier elements in the ashes is likely only an artifact) and only include this timestep as a visual indication of how the ashes get compressed into a sphere.
