Wing Ip just had an interesting Iapetus-related paper published in GRL.

Just noticed I did not address moonlets below synchronous altitude and above the Roche limit. With moons above the synchronous altitude experiencing an acceleration in their orbit due to tidal effects, it seems the moons below synchronous altitude would experience a deceleration from those same forces.
(although realize since the moonlet winds up lower, it still winds upgoing faster. Such is the weirdness of orbital mechanics) I suspect tidal interactions among such moons and moonlets would be tough to calculate 'post mortem' considering. The degree of moltenidity of the primary and the rigidity of the moonlet would all affect how fast the orbital energy would dissipate. I suspect bodies such as moonlets might be rather porous, rocky, dusty and void filled. I suspect such bodies might be especially efficient at being susceptible to tidal interactions. |
