摘要

The problem of planetary accretion in a jet stream is studied using the model developed by Alfvén and Arrhenius. We find that there are basically three types of planetary accretion: namely, fast process τc < τi, slow process τc ~ τi and delayed process τc > τi where τc is the characteristic time of the occurrence of catastrophic accretion and τi the time-scale of mass injection to the planetary system (≃3×108 yr). These different time scales of accretion are found to be closely related to the primordial thermal profiles and equatorial inclinations of the planets. Finally, Venus' retrograde rotational spin is shown to be a possible result of accretion process in a jet stream.
