Suppression of Resonant Overstability at Sharp Migration Gradients
Konstantin Batygin, Ian R. Brunton, Alessandro Morbidelli
Mean-motion resonances are expected to frequently arise at the inner edges of protoplanetary disks, where planet-disk interactions facilitate large-scale orbital convergence. Under…
Origins of Compact Mean-Motion Resonances: Evidence for Long-Range Migration and the Case of Kepler-36
Konstantin Batygin, Alessandro Morbidelli
The observed census of resonant extrasolar planets spans a tantalizing display of orbital architectures, ranging from familiar 2:1 and 3:2 mean-motion commensurabilities to nearly…
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…
Compositional Outcomes of Earth Formation from a Narrow Ring
Katherine I. Dale, Alessandro Morbidelli, David C. Rubie +1
We address Earth formation from an elemental perspective, using a method similar to Rubie et al. (2015) but with updates from Dale et al. (2023) to simulate the chemical evolution…
Reassessing the origin and evolution of Ecliptic Comets in the Planet-9 Scenario
Rafael Ribeiro, Andre Izidoro, Alessandro Morbidelli +2
A group of newly observed extreme trans-Neptunian objects exhibit unexpected orbital confinement, characterized by the alignment of orbital angular momentum vectors and apsidal lin…
