The massive cores of the giant planets are thought to have formed in a gas disk by the accretion of pebble-sized particles whose accretional cross-section was enhanced by aerodynamic gas drag1,2. A commonly held view is that the terrestrial planet system formed later (30–200 Myr after the dispersal of the gas disk) by giant collisions of tens of lunar- to Mars-sized protoplanets3,4. Here we propose, instead, that the terrestrial planets of the Solar System formed earlier by the gas-driven… Expand

A terrestrial convergence
The standard model of terrestrial planet formation ignores the role of orbital migration of planetary embryos. A new scenario shows how migration may have sculpted the inner Solar System’s orbitalExpand


Planet heating prevents inward migration of planetary cores
It is reported that asymmetries in the temperature rise associated with accreting infalling material produce a force (which gives rise to an effect that is called ‘heating torque’) that counteracts inward migration and provides a channel for the formation of giant planets. Expand
Formation of planetary systems by pebble accretion and migration
Super-Earths – planets with sizes between the Earth and Neptune – are found in tighter orbits than that of the Earth around more than one third of main sequence stars. It has been proposed thatExpand
Rapid growth of gas-giant cores by pebble accretion
The observed lifetimes of gaseous protoplanetary discs place strong constraints on gas and ice giant formation in the core accretion scenario. The approximately 10-Earth-mass solid core responsibleExpand
Formation of the terrestrial planets in the solar system around 1 au via radial concentration of planetesimals
No planets exist inside the orbit of Mercury and the terrestrial planets of the solar system exhibit a localized configuration. According to thermal structure calculation of protoplanetary disks, aExpand
Eccentricity excitation and merging of planetary embryos heated by pebble accretion
Context: Planetary embryos can continue to grow by pebble accretion until they become giant planet cores. Simultaneously, these embryos mutually interact and also migrate due to torques arising fromExpand
Torques Induced by Scattered Pebble-flow in Protoplanetary Disks
In the current planet formation paradigm, gravitational torques exerted by the gas in protoplanetary disks play a central role in determining the long-term orbital evolution of planetary embryos.Expand
A low mass for Mars from Jupiter’s early gas-driven migration
Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.

The structure of protoplanetary discs around evolving young stars
The formation of planets with gaseous envelopes takes place in protoplanetary accretion discs on time scales of several million years. Small dust particles stick to each other to form pebbles,Expand
Making the Terrestrial Planets: N-Body Integrations of Planetary Embryos in Three Dimensions
We simulate the late stages of terrestrial-planet formation using N-body integrations, in three dimensions, of disks of up to 56 initially isolated, nearly coplanar planetary embryos, plus JupiterExpand
Orbital Migration of Low-mass Planets in Evolutionary Radiative Models: Avoiding Catastrophic Infall
Outward migration of low-mass planets has recently been shown to be a possibility in non-barotropic disks. We examine the consequences of this result in evolutionary models of protoplanetary disks.Expand
