Making the Solar System

We model the early stages of planet formation in Solar System, including continual planetesimal formation, and pebble accretion onto planetary embryos an evolving disk driven by a wind. The aim is to constrain aspects that have large uncertainties matching key characteristics System. produces good fit these for narrow range parameter space. Planetary growth beyond ice line dominated accretion. Planetesimal more important inside line. Pebble slowed higher temperatures, partial removal inflowing pebbles further out disk, increased radial velocities due gas advection. terrestrial planets are prevented from accreting much water because reach isolation mass before enters terrestrial-planet region. When only considered, typically remain near their initial or grow pebble-isolation mass. Adding allows Mars-sized objects form line, giant-planet cores over wider region In occupied Mercury, Stokes numbers small. This delays stunts growth, so low-mass can here.
