Unlocking the Solar System’s Secrets: The Journey of Giant Planets and Distant Trans-Neptunian Objects
V. V. Emel’yanenko’s study of the Nice model shows how migrating giant planets scattered planetesimals, forming distant trans-Neptunian objects (TNOs) like Sedna. Simulations over 4 billion years reveal that specific planetary resonances and disk conditions can reproduce the Solar System’s structure and explain TNOs.
Understanding the Colors and Movements of Trans-Neptunian Objects: A Dive into Their Origins and Dynamics
The study analyzes 696 trans-Neptunian objects (TNOs) to explore their sizes, colors, and shapes, linking them to their formation regions and migration. Two main color groups, NIRF and NIRB, reveal distinct origins, with Cold Classicals being mostly NIRF and dynamically excited classes showing mixed populations. The findings support models of Solar System evolution and provide insights into planetesimal formation and Neptune's migration.
