The Edges of Planetary Systems: Falling Off the Kuiper Cliff in a Dissipating Gas Disk
Rixin Li, Eugene Chiang
Probably the last planetesimals to have formed from dust in the solar nebula are Cold Classical Kuiper belt objects (CCKBOs). To the extent that they are isolated and unchanged sin…
Two-stage disruption of resonant chains
Nick Choksi, Yoram Lithwick, Eugene Chiang +1
TESS is enabling the discovery of transiting planets around young stars. These observations suggest that most close-in planets were born in chains of mean-motion resonances that br…
The Resonant Remains of Broken Chains from Major and Minor Mergers
Rixin Li, Eugene Chiang, Nick Choksi +1
TESS and Kepler have revealed that practically all close-in sub-Neptunes form in mean-motion resonant chains, most of which unravel on timescales of 100 Myr. Using N-body integrati…
The Prevalence of Resonance Among Young, Close-in Planets
Fei Dai, Max Goldberg, Konstantin Batygin +11
Multiple planets undergoing disk migration may be captured into a chain of mean-motion resonances with the innermost planet parked near the disk's inner edge. Subsequent dynamical…
