A large fraction of giant planets have gaseous envelopes that are limited to about 10 % of their total mass budget. Such planets are present in the Solar System (Uranus, Neptune) and are frequently observed in short periods around other stars (the so-called Super-Earths). In contrast to these observations, theoretical calculations based on the evolution of hydrostatic envelopes argue that such low mass envelopes cannot be maintained around cores exceeding five Earth masses. Instead, under… Expand
Quasi-static contraction during runaway gas accretion onto giant planets.
Gas-giant planets, like Jupiter and Saturn, acquire massive gaseous envelopes during the approximately 3 Myr-long lifetimes of protoplanetary discs. In the core accretion scenario, the formation of aExpand
A Limit on Gas Accretion onto Close-in Super-Earth Cores from Disk Accretion
The core-accretion model predicts that planetary cores as massive as super-Earths undergo runaway gas accretion to become gas giants. However, the exoplanet census revealed the prevalence ofExpand
Formation of planetary systems by pebble accretion and migration : Growth of gas giants
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract their gaseous envelope. Previously, we have studied the growth and migration of an isolated planet in anExpand
Envelopes of embedded super-Earths II. Three-dimensional isothermal simulations.
Massive planetary cores embedded in protoplanetary discs are believed to accrete extended atmospheres, providing a pathway to forming gas giants and gas-rich super-Earths. The properties of theseExpand
Gas flow around a planet embedded in a protoplanetary disc. Dependence on planetary mass
The three-dimensional structure of the gas flow around a planet is thought to influence the accretion of both gas and solid materials. In particular, the outflow in the mid-plane region may preventExpand
Unified Simulations of Planetary Formation and Atmospheric Evolution. II. Rapid Disk Clearing by Photoevaporation Yields Low-mass Super-Earth Atmospheres
Super-Earths possess low-mass H$_2$/He atmospheres (typically less than 10% by mass). However, the origins of super-Earth atmospheres have not yet been ascertained. We investigate the role of rapidExpand
Formation of planetary systems by pebble accretion and migration. How the radial pebble flux determines a terrestrial-planet or super-Earth growth mode
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
Inner rocky super-Earth formation: distinguishing the formation pathways in viscously heated and passive discs
The formation of super-Earths is strongly linked to the structure of the protoplanetary disc, which determines growth and migration. In the pebble accretion scenario, planets grow to the pebbleExpand
Suppression of atmospheric recycling of planets embedded in a protoplanetary disc by buoyancy barrier
The ubiquity of super-Earths poses a problem for planet formation theory to explain how they avoided becoming gas giants. Rapid recycling of the envelope gas of planets embedded in a protoplanetaryExpand
The imprint of the protoplanetary disc in the accretion of super-Earth envelopes
Super-Earths are by far the most dominant type of exoplanet, yet their formation is still not well understood. In particular, planet formation models predict that many of them should have accretedExpand


Separating gas-giant and ice-giant planets by halting pebble accretion
In the solar system giant planets come in two flavours: gas giants (Jupiter and Saturn) with massive gas envelopes, and ice giants (Uranus and Neptune) with much thinner envelopes around their cores.Expand
Formation of Giant Planets: Dependences on Core Accretion Rate and Grain Opacity
We have investigated the formation of gaseous envelopes of giant planets with wide ranges of parameters through quasi-static evolutionary simulations. In the nucleated instability model, rapid gasExpand
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
Forming the cores of giant planets from the radial pebble flux in protoplanetary discs
The formation of planetary cores must proceed rapidly in order for the giant planets to accrete their gaseous envelopes before the dissipation of the protoplanetary gas disc (less than or similar toExpand
The growth of planets by pebble accretion in evolving protoplanetary discs
The formation of planets depends on the underlying protoplanetary disc structure, which in turn influences both the accretion and migration rates of embedded planets. The disc itself evolves on timeExpand
Formation of the giant planets
Observational constraints on interior models of the giant planets indicate that these planets were all much hotter when they formed and they all have rock and/or ice cores of ten to thirty earthExpand
In the core-accretion model, the nominal runaway gas-accretion phase brings most planets to multiple Jupiter masses. However, known giant planets are predominantly Jupiter mass bodies. ObtainingExpand

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
Hydrodynamics of embedded planets' first atmospheres - II. A rapid recycling of atmospheric gas
Following Paper I we investigate the properties of atmospheres that form around small protoplanets embedded in a protoplanetary disc by conducting hydrodynamical simulations. These are now extendedExpand
