TIDAL EVOLUTION OF A SECULARLY INTERACTING PLANETARY SYSTEM

Journal Article · · Astrophysical Journal
In a multi-planet system, a gradual change in one planet's semimajor axis will affect the eccentricities of all the planets, as angular momentum is distributed via secular interactions. If tidal dissipation in the planet is the cause of the change in semimajor axis, it also damps that planet's eccentricity, which in turn also contributes to the evolution of all the eccentricities. Formulae quantifying the combined effects on the whole system due to semimajor axis changes, as well as eccentricity damping, are derived here for a two-planet system. The CoRoT 7 system is considered as an example.
