Planet Formation in Binaries [PDF]

open access: yes, 2015
Spurred by the discovery of numerous exoplanets in multiple systems, binaries have become in recent years one of the main topics in planet formation research. Numerous studies have investigated to what extent the presence of a stellar companion can affect the planet formation process.

On planet formation in HL Tau [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2015
Abstract We explain the axisymmetric gaps seen in recent long-baseline observations of the HL Tau protoplanetary disc with the Atacama Large Millimetre/Submillimetre Array (ALMA) as being due to the different response of gas and dust to embedded planets in protoplanetary discs. We perform global, three-dimensional dusty smoothed particle

Stokes trapping and planet formation [PDF]

open access: yes, 2007
It is believed that planets are formed by aggregation of dust particles suspended in the turbulent gas forming accretion disks around developing stars. We describe a mechanism, termed 'Stokes trapping', by which turbulence limits the growth of aggregates

Photophoresis boosts giant planet formation [PDF]

open access: yes, 2013
In the core accretion model of giant planet formation, a solid protoplanetary core begins to accrete gas directly from the nebula when its mass reaches about 5 earth masses.

A tale of planet formation: from dust to planets [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2020
AbstractThe characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations.

Catching a planet: A tidal capture origin for the exomoon candidate Kepler 1625b I [PDF]

open access: yes, 2018
The (yet-to-be confirmed) discovery of a Neptune-sized moon around the ~3.2 Jupiter-mass planet in Kepler 1625 puts interesting constraints on the formation of the system.

Planet formation around low mass stars: the moving snow line and super-Earths [PDF]

open access: yes, 2006
We develop a semi-analytic model for planet formation during the pre-main sequence contraction phase of a low mass star. During this evolution, the stellar magnetosphere maintains a fixed ratio between the inner disk radius and the stellar radius. As the

Stochasticity & Predictability in Terrestrial Planet Formation [PDF]

open access: yes, 2016
Terrestrial planets are thought to be the result of a vast number of gravitational interactions and collisions between smaller bodies. We use numerical simulations to show that practically identical initial conditions result in a wide array of final ...

Constraining planet formation around 6M⊙-8M⊙ stars [PDF]

open access: yes, 2020
Identifying planets around O-type and B-type stars is inherently difficult; the most massive known planet host has a mass of only about 3M⊙. However, planetary systems which survive the transformation of their host stars into white dwarfs can be detected
