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.

Planet Formation [PDF]

open access: yes, 2021
Our galaxy is full with planets. We now know that planets and planetary systems are diverse and come with different sizes, masses and compositions, as well as various orbital architectures. Although there has been great progress in understanding planet formation in the last couple of decades, both observationally and theoretically, several fundamental ...

On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]

open access: yes, 2015
PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).

Effect of pebble flux-regulated planetesimal formation on giant planet formation [PDF]

open access: yes, 2020
Context. The formation of gas giant planets by the accretion of 100 km diameter planetesimals is often thought to be inefficient. A diameter of this size is typical for planetesimals and results from self-gravity.

Simulations for Terrestrial Planets Formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
AbstractWe investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated. In the model, the perturbations from Jupiter and Saturn are considered.

Planet Formation via Gravitational Instability [PDF]

open access: yes, 2021
Some observed exoplanets cannot be explained in the standard core accretion paradigm. An alternative formation model, planet formation via gravitational instability (GI), has been proposed as a formation mechanism instead.

Planetesimal fragmentation and giant planet formation: the role of planet migration [PDF]

open access: yes, 2014
In the standard model of core accretion, the cores of the giant planets form by the accretion of planetesimals. In this scenario, the evolution of the planetesimal population plays an important role in the formation of massive cores. Recently, we studied

Influence of Stellar Multiplicity On Planet Formation. IV. Adaptive Optics Imaging of Kepler Stars With Multiple Transiting Planet Candidates [PDF]

open access: yes, 2015
The Kepler mission provides a wealth of multiple transiting planet systems (MTPSs). The formation and evolution of multi-planet systems are likely to be influenced by companion stars given the abundance of multiple stellar systems. We study the influence
