 stract: In the past two decades\, transit surveys have revealed a populati
 on of sub-Neptunes—planets with thick atmospheres that must have complet
 ed their growth within protoplanetary disks. During this stage\, gravitati
 onal interactions with the disk drive planet migration\, often trapping ne
 ighboring planets into mean-motion resonances. Yet most exoplanets today a
 re not in resonance\, indicating that dynamical instabilities must have di
 srupted many primordial resonances. My research seeks to uncover the histo
 ry of planet formation from these orbital architectures. In this talk\, I 
 will first show how planet formation leaves imprints in resonant systems s
 uch as TRAPPIST-1. I will then demonstrate how wide companion planets can 
 destabilize the primordial resonances of inner terrestrial planets and eve
 n trigger Moon-forming impacts\, as in our Solar System. \nShort Bio: Shu
 o Huang is currently a TDLI postdoc. He obtained Joint PhD at Tsinghua Uni
 versity (advisor Chris Ormel) and Leiden Observatory (advisor Simon Porteg
 ies Zwart) in 2026. His research focuses on the orbital dynamics and plane
 t formation.\n\n \n\nhttps://indico-tdli.sjtu.edu.cn/event/5383/
