Numerical Simulations of Dust Circulation by Radiation Pressure in Protoplanetary Disks with Puffed-up Inner Rim

Abstract

The meter-sized particles rapidly fall into the central star due to the gas drag force, before planetesimal formation. Thus, some outflow mechanisms are required for planetesimal formation. We consider the stellar radiation pressure induced the dust outflow for a weak turbulent disk with the puffed-up inner rim, where magnetorotational instability is induced because of thermal ionization of alkali metal. Our main objective is to investigate a possibility for the realization of dust circulation in the protoplanetary disk. We will report results by new numerical simulation code.
