[PPS21-19] Effect of wave propagation for a planet-induced gap formation in protoplanetary disks
Keywords:protoplanetary disk, disk-planet interaction, disk evolution
According to our analysis with the one-dimensional model, the propagation and damping of the density wave excited by the planet is closely related to the gap depths and widths (Kanagawa et al 2015). Therefore, we computed the gap structure around the planet using FARGO, which is an open source code for hydrodynamic simulation. Results of the simulation show that in the case with the large planet (such as Jupiter), low-mode waves (in particular m=2 mode) become stronger than high-mode waves. Because the low-mode waves would be difficult to be damped by shock dispersion, these waves can propagate farther from the planet than high-mode waves.
In this talk, I will illustrate the results and discuss the wave propagation and gap formation for large planets.
