Particles ejected by collisions simulated with the DISPH method using SESAME/ANEOS EOS (top), Tillotson EOS (middle), and HM80 EOS (bottom), for initial angular momenta L_imp = 3.0, 5.0, and 7.0 × 10³⁶ kg m² s⁻¹ (from left to right). These panels display the state of the system at the final time of the simulation. The dotted circle indicates Uranus’s Roche radius. The components are color-coded as follows: target ice (dark blue), impactor ice (light blue), impactor rock (gray), and atmosphere (green).
