We have introduced self-consistent spin, tidal and dynamical equations of motion into REBOUNDx, a library of additional effects for the popular N-body integrator REBOUND. The equations of motion used are derived from the constant time lag approximation to the equilibrium tide model of tidal friction. These effects will allow the study of a variety of systems where the full dynamical picture cannot be encapsulated by point particle dynamics. We provide several test cases and benchmark the code's performance against analytic predictions. The open-source code is available in the most recent release of REBOUNDx.

  1. Tidal evolution of packed moon systems around an Earth-mass planet

    astro-ph.EP 2026-07 conditional novelty 5.0 of 10

    Including tidal migration cuts the maximum stable moon count around an Earth-mass planet to about two Moon-sized, three Pluto-sized, or five Ceres-sized moons, confined to narrow orbital-spacing windows.
