From pebbles to planets: planetesimal formation and pebble accretion
Abstract
From pebbles to planets: planetesimal formation and pebble accretion Abstract: Even though thousands of extrasolar planetary systems have been detected, a comprehensive picture of how planets are formed from their natal protoplanetary disks remains to be drawn. I will review our current understanding of the dust-gas dynamics in protoplanetary disks and its consequences on the formation of planets via the core accretion scenario. Specifically, I will examine how and under what conditions cm-/mm-sized dust pebbles can actively concentrate themselves to high density for km-scale planetesimals to form, the initial mass function of planetesimals, and how pebble accretion assists planet formation, along with some supporting observational evidence.
