  Iapetus Hypothetical Sub-Satellite Re-Visited and it Reveals Celestial Body Formation Process in The Primary-Centric Framework
  Author(s): Bijay K. Sharma*
  
  Levison, et al., have carried out a simulation of the hypothetical Sub-Satellite (SS) of Iapetus, the third largest walnut-shaped moon of Saturn, and examined its contributions towards de-spinning of Iapetus and if it could possibly give rise to an ancient equatorial ridge as confirmed by close fly-by Cassini mission in 2004 for different mass ratios ‘q’=SS mass/Iapetus mass. The same study has been carried out inprimary-centric frame-work analytically in the present paper. It is found that initially when Iapetus was formed at Roche limit in circum-saturnian impact generated disc it was spinning at 13 hours spin period. Subsequently in few hundred years after the formation of the hypothetical Sub-Satellite (SS), it de-spunto 16 hours spin-period, simultaneously it cooled and froze its contemporary hydro-static equilibrium shape which we observe today as non-hydrostatic equ..
