In this paper we argue that differential rotation can possibly sustain hydrodynamic turbulence in the absence of magnetic field. We explain why the non-linearities of the hydrodynamic equations (i.e. turbulent diffusion) should not be neglected, either as a simplifying approximation or based on boundary counditions. The consequences of lifting this hypothesis are studied for the flow stability and the enhanced turbulent transport. We develop a simple general model for the energetics of… 
Particle-Gas Dynamics and Primary Accretion
Abstract. Planetesinial bow shocks would have existed during the chondrule forniation epoch if proto-.Jupiter formed within a few Myr of CAI forniation and if the protoplanetary nebula persisted for
The formation of a gas giant planet in a viscously evolved protoplanetary disk within the core accretion model
The gas giant planets’ formation processes in a viscously evolved protoplanetary disk are studied in the context of the core accretion model. In this paper, we follow the entire formation process of
