Influences of protoplanet-induced three-dimensional gas flow on pebble accretion

Abstract: Context. Pebble accretion is among the major theories of planet formation. Aerodynamically small particles, called pebbles, are highly affected by the gas flow. A growing planet embedded in a protoplanetary disk induces three-dimensional (3D) gas flow. In our previous work, Paper I, we focused on the shear regime of pebble accretion and investigated the influence of planet-induced gas flow on pebble accretion. In Paper I, we found that pebble accretion is inefficient in the planet-induced gas flow compared to … Show more

“…The following columns give the simulation name, the size of the Bondi radius of the planet, the size of the Hill radius of the planet, the size of the inner boundary, the size of the outer boundary, the size of the limited part of the calculation domain (Sect. 2.3), the Mach number of the headwind, the length of the calculation time, and the regime of the planet-induced gas flow (Kuwahara & Kurokawa 2020b, as we focus on the range of the turbulence strength considered in this study, the turbulence likely affects the dust only. The viscosity suppresses the 3D flow only when its α-viscous coefficient is large, α diff 10 −2 (Fung et al 2015;Lambrechts & Lega 2017).…”
