However, the occurrence of observed resonant chains, such as the notable TRAPPIST-1 system, is relatively low. This suggests that the majority of these chains become destabilized after the dissipation of the protoplanetary disk. Stellar tides, especially the wavelike dynamical tide, could be proposed as potential contributors to the destabilization of resonant chains. The dissipation of the dynamical tide, because of the frequency-dependant tidal excitation of stellar oscillation eigenmodes, potentially leads to a boost in migration for the close-in planets and disrupts the fragile stability of resonant chains. Thus, we investigate the influence of the stellar dynamical tide on multi-planet systems with taking their dissipation into account in the N-body code Posidonius. Notably, this research represents the first exploration of the impact of frequency-dependent dynamical tides on multi-planet systems.</p> Dewey 520 26 Département d'astronomie 12 false Proceedings of the International Astronomical Union, Volume 18, Symposium S382: Complex Planetary Systems II: Latest Methods for an Interdisciplinary Approach f9b7ba45-5f72-48bf-ab25-93cc2a6d7b95 Proceedings chapter (Published version) Public Article_scientifique_from_crossref.pdf 292847 application/pdf CC BY-NC-ND-4.0 558a0b20c2916c2b90e709cf0f38dd724447e4809ea4a48f0f8670106a0804c8 openAccess Faculté des sciences / Département d'astronomie
