C depletion and sintering outcomes of NC planetesimals of varying sizes. The bodies have R_c = 10, 20,...100 km, but their x locations are their final radii. Each bar represents the layering of a body in mass fraction, from its center (bottom) to its surface (top). The green portions of each bar have more than 10% of solid carbon retained, while the ivory parts are the opposite. The cross-pattern shaded region is completely sintered with a porosity of <0.03, below the pore closure porosity predicted by SCP packing geometry.
