The 5 Myr migration rate to the asteroids Phaethon (green), UD (blue), and YC (pink). The upper four panels show the transportation from the asteroid family (2) Pallas via the 5:2J (a) and 8:3J (b) MMRs. Panels c and d present migrations from the (329) Svea and (142) Polana families via the 3:1J resonance. On the left are the results obtained with Orbit9, and on the right those with Rebound/Mercurius. Orbit9 displays a noticeably greater transfer efficiency, particularly for asteroids Phaethon and UD, with around 50% of TPs arriving from the resonances in Pallas and Svea families. In Mercurius, the 5:2J and 8:3J MMRs show almost identical transportation to all three asteroids: the curves on the right in (a) and (b) are overlapping. These lines are separated in the lower two panels for Mercurius (panels on the right side of panels c and d, showing the highest arrival efficiency to Phaethon, a slightly lower efficiency to UD, and the lowest to YC. More details are given in the main text and Tables 1–3.
