Abstract The final stage in the formation of terrestrial planets consists of the accumulation of ∼1000-km “planetary embryos” and a swarm of billions of 1–10 km “planetesimals.” During this process, water-rich material is accreted by the terrestrial planets via impacts of water-rich bodies from beyond roughly 2.5 AU. We present results from five high-resolution dynamical simulations. These start from 1000–2000 embryos and planetesimals, roughly 5–10 times more particles than in previous… Expand
High-resolution simulations of the final assembly of Earth-like planets. 2. Water delivery and planetary habitability.
TLDR
A new model for water delivery to terrestrial planets in dynamically calm systems, with low-eccentricity or low-mass giant planets-such systems may be very common in the Galaxy is presented. Expand
Simulations for Terrestrial Planets Formation
We investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk hasExpand
Terrestrial planet formation with strong dynamical friction
Abstract We have performed 8 numerical simulations of the final stages of accretion of the terrestrial planets, each starting with over 5× more gravitationally interacting bodies than in any previousExpand
Simulations for terrestrial planets formation
In this paper, the formation of terrestrial planets in the late stage of planetary formation is investigated using the two-planet model. At that time, the protostar formed for about 3 Ma and the gasExpand
Dynamical Models of Terrestrial Planet Formation
We review the problem of the formation of terrestrial planets, with particular emphasis on the interaction of dynamical and geochemical models. The lifetime of gas around stars in the process ofExpand

Abstract Terrestrial planets form in a series of dynamical steps from the solid component of circumstellar disks. First, km-sized planetesimals form likely via a combination of sticky collisions,Expand

Abstract To date, no accretion model has succeeded in reproducing all observed constraints in the inner Solar System. These constraints include: (1) the orbits, in particular the smallExpand

Gas giant planets are far easier than terrestrial planets to detect around other stars, and they are thought to form much more quickly than terrestrial planets. Thus, in systems with giant planets,Expand
