We hypothesize that planets are made by tidal downsizing of migrating giant planet embryos. The proposed scheme for planet formation consists of these steps: (i) a massive young protoplanetary disc fragments at R ∼ several tens to hundreds of au on gaseous clumps with masses of a few Jupiter masses; (ii) the clumps cool and contract, and simultaneously migrate closer in to the parent star; (iii) as earlier suggested by Boss, dust sediments inside the gas clumps to form terrestrial mass solid… Expand

The migrating embryo model for disk evolution
– A new view of disk evolution is emerging from self-consistent numerical simulation modeling of the formation of circumstellar disks from the direct collapse of prestellar cloud cores. This hasExpand
Early evolution of clumps formed via gravitational instability in protoplanetary disks; precursors of Hot Jupiters?
Although it is fairly established that Gravitational Instability (GI) should occur in the early phases of the evolution of a protoplanetary disk, the fate of the clumps resulting from diskExpand
Circumstellar disks of the most vigorously accreting young stars
Subaru-HiCIAO observations on FU Orionis objects revealed asymmetric structures on 102 to 103 AU scales of circumstellar disks and envelopes that can indeed be explained by strong gravitational instabilities occurring at the beginning of the disk formation phase. Expand
Giant Planet Formation and Migration
Planets form in circumstellar discs around young stars. Starting with sub-micron sized dust particles, giant planet formation is all about growing 14 orders of magnitude in size. It has becomeExpand
Fragmenting protostellar discs: properties and observational signatures
Using numerical hydrodynamic simulations, we study the gravitational fragmentation of an unstable protostellar disc formed during the collapse of a pre-stellar core with a mass of 1.2 M_sun. TheExpand
Planetary system formation in thermally evolving viscous protoplanetary discs
While the simulations are successful at forming populations of low- and intermediate-mass planets with short orbital periods, similar to those that are being observed by ground- and space-based surveys, the models fail to form any gas giant planets that survive migration into the central star.

Orbital features of distant trans-Neptunian objects induced by giant gaseous clumps
Context: The discovery of distant trans-Neptunian objects has led to heated discussions about the structure of the outer Solar System. Aims: We study the dynamical evolution of small bodies from theExpand
Migration of Giant Gaseous Clumps and Structure of the Outer Solar System
Abstract New data on the distribution of distant trans-Neptunian objects and on the properties of comets indicate the importance of dynamical processes in the outer part of the protoplanetary disk inExpand

Accretion bursts in low-metallicity protostellar disks
The early evolution of protostellar disks with metallicities in the $Z=1.0-0.01~Z_\odot$ range was studied with a particular emphasis on the strength of gravitational instability and the nature ofExpand


Rapid planetesimal formation in turbulent circumstellar disks
It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes. Expand
Evolution of the Solar Nebula. IV. Giant Gaseous Protoplanet Formation
The discovery of the first extrasolar planets, with masses in the range of ~0.5 MJup (MJup = Jupiter mass) to ~3 MJup, demands a reevaluation of theoretical mechanisms for giant planet formation.Expand
