Spin-orbital Tidal Dynamics and Tidal Heating in the TRAPPIST-1 Multiplanet System
Spin-orbital Tidal Dynamics and Tidal Heating in the TRAPPIST-1 Multiplanet System
We perform numerical simulations of the TRAPPIST-1 system of seven exoplanets orbiting a nearby M dwarf, starting with a previously suggested stable configuration. The long-term stability of this configuration is confirmed, but the motion of planets is found to be chaotic. The eccentricity values are found to vary within finite …
