Planetesimals to protoplanets–II. Effect of debris on terrestrial planet formation
methods N-body simulations–methods numerical–Solar system formation–planetary systems formation
2015/12/25
In this paper, we extend our numerical method for simulating terrestrial planet formation to include dynamical friction from the unresolved debris component. In the previous work, we implemented a rub...
PLANETESIMALS TO PROTOPLANETS. I. EFFECT OF FRAGMENTATION ON TERRESTRIAL PLANET FORMATION
n-body simulations planetary systems solar system
2015/12/25
We present results from a dozen direct N-body simulations of terrestrial planet formation with various initial conditions. In order to increase the realism of our simulations and investigate theeffect...
Elemental abundance differences in the 16 Cygni binary system: a signature of gas giant planet formation?
Elemental abundance differences signature planet formation
2011/10/20
The atmospheric parameters of the components of the 16Cygni binary system, in which the secondary has a gas giant planet detected, are measured accurately using high quality observational data. Abunda...
Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models
Detailed Abundances Solar Twins Constraining Planet Formation Models
2011/10/10
Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B is known to host a g...
Giant Planet Formation by Disk Instability in Low Mass Disks?
Giant Planet Formation Disk Instability Low Mass Disks
2011/1/11
Forming giant planets by disk instability requires a gaseous disk that is massive enough to become gravitationally unstable and able to cool fast enough for self-gravitating clumps to form and survive...
The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations
the initial surface density profiles the disc on giant planet formation
2011/1/10
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial c...
Runaway Growth During Planet Formation: Explaining the Size Distribution of Large Kuiper Belt Objects
circumstellar matter Kuiper belt planetary systems general planets and satellites
2010/11/9
Runway growth is an important stage in planet formation during which large protoplanets form,
while most of the initial mass remains in small planetesimals. The amount of mass converted into large pr...
High-resolution spectroscopic view of planet formation sites

2010/11/15
Theories of planet formation predict the birth of giant planets in the inner, dense, and
gas-rich regions of the circumstellar disks around young stars. These are the regions from which strong CO emi...
Towards the Rosetta Stone of planet formation
Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/5
Transiting exoplanets (TEPs) observed just about 10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong constraints on sever...
