[PPS21-P18] Jovian core formation at the boundaries of dead zone: dependence on the gas surface density ditribution
Keywords:jovian planet, core, dead zone, gas surface density distribution
In this simulation, a gas surface density distribution obtained from Lyla et al.(2009) is adopted. We changed the heights of two peaks in the distribution and checked the dependence of the largest mass on the height. We confirmed that the migration timescale of a planet inversely proportional to the peak height. It has been shown that the largest mass depends on the migration timescale logarithmically. This result indicates that the time evolution of the gas surface density cannot be neglected in the formation of a core. We will present the simulation results taking account of the time evolution of gas surface density distribution.
