Unexpected Near-Resonant and Metastable States of Young Multi-Planet Systems

Zhecheng Hu, Fei Dai, Wei Zhu +4

Recent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution…

Two-source terrestrial planet formation with a sweeping secular resonance

Max Goldberg, David Nesvorný, Alessandro Morbidelli

The models that most successfully reproduce the orbital architecture of the Solar System terrestrial planets start from a narrow annulus of material that grows into embryos and the…

Dynamical Evolution of Planetary Systems

Antoine C. Petit, Gabriele Pichierri, Max Goldberg +1

Planetary systems can evolve dynamically even after the planets themselves have fully formed, and there is circumstantial evidence that most planetary systems become unstable after…

Close-in compact super-Earth systems emerging from resonant chains: slow destabilization by unseen remnants of formation

Max Goldberg, Antoine C. Petit

Planet formation simulations consistently predict compact systems of numerous small planets in chains of mean motion resonances formed by planet-disk interaction, but transiting pl…

Nutation-orbit resonances: The origin of the chaotic rotation of Hyperion and the barrel instability

Max Goldberg, Konstantin Batygin

While numerous planetary and asteroid satellites show evidence for non-trivial rotation states, none are as emblematic as Hyperion, which has long been held as the most striking ex…

TOI-4495: A Pair of Aligned, Near-Resonant Sub-Neptunes that Likely Experienced Overstable Migration

Mu-Tian Wang, Fei Dai, Hui-Gen Liu +24

We report the discovery of a sub-Neptune and a Neptune-like planet (, ) orbiting the F-type star TOI-449…
