Evolution of the SFD of Hilda asteroids relative to the initial population. Top: median SFD (left) and ratio with respect to the initial SFD in the sub-kilometre size range for the S10 (red), S31 (blue), and S32 (green) scenarios. Dashed-dotted lines represent the initial SFD. Bottom: SFD of catastrophically disrupted bodies (left) and ratio of catastrophically disrupted bodies with respect to the initial SFD (right) for the S10 (red), S31 (blue), and S32 (green) scenarios. Solid lines represent simulations conducted with icy targets’ scaling laws, while dashed lines indicate simulations with basaltic targets.
