Numerical simulations of type III planetary migration – II. Inward migration of massive planets [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2008
We present a numerical study of rapid, so called type III migration for Jupiter-sized planets embedded in a protoplanetary disc. We limit ourselves to the case of outward migration, and study in detail its evolution and physics, concentrating on the structure of the co-rotation and circumplanetary regions, and processes for stopping migration.

RADIATIVE TRANSFER AND PLANETARY MIGRATION IN PROTOPLANETARY DISKS [PDF]

open access: yes, 2008
Planetary migration has become one of the most important processes in planet formation since the first discovery of an exoplanet around 51Peg. A decade after the discovery, the total number of exoplanets has increased to about three hundred. Theoretical

Influence of migration models and thermal torque on planetary growth in the pebble accretion scenario [PDF]

open access: yes, 2020
Low-mass planets that are in the process of growing larger within protoplanetary disks exchange torques with the disk and change their semi-major axis accordingly.

Building bridges for migration in a planetary context [PDF]

open access: yesEuropean Journal of Public Health, 2019
Abstract Europe is experiencing high volumes of migration, both within and to the region. Globally, several factors contributing to high-volume migration, ranging from economic ones (migrant workers) to forced displacement caused by conflict, persecution and climate changes (draught or other extreme ...

Dynamical architectures of planetary systems induced by orbital migration [PDF]

open access: yes, 2010
The aim of this talk is to present the most recent advances in establishing plausible planetary system architectures determined by the gravitational tidal interactions between the planets and the disc in which they are embedded during the early epoch ...

Towards a More Just Canadian Education-migration System: International Student Mobility in Crisis

open access: yesStudies in Social Justice, 2022
Education-migration, or the multi-step recruitment and retention of international students as immigrants, is an increasingly important component of both higher education and so-called highly-skilled migration.

THE SEISMICITY MIGRATION STUDY BASED ON SPACE-TIME DIAGRAMS

open access: yesГеодинамика и тектонофизика, 2015
Seismicity migration is studied by a new method based on space-time diagrams and a combination of cluster and regression analyses. Data from the global and Baikal regional earthquake catalogues are analysed with the application of the specially designed ...

Streaming Torque with Turbulent Diffusion

open access: yesThe Astrophysical Journal
Fast type I migration of (proto)planets poses a challenging problem for the core accretion formation scenario. We found that the dust-induced “Streaming Torque” (ST) may slow down or even reverse the planet migration in Q. Hou & C. Yu.

Numerical simulations of type III planetary migration [PDF]

open access: yes, 2008
Planets are believed to form in primordial gas-dust discs surrounding newborn stars. An important breakthrough in our understanding of planetary formation was the discovery of extra-solar planets around sun-like stars, especially the frequent occurrence ...

Making systems of Super Earths by inward migration of planetary embryos [PDF]

open access: yes, 2013
International audienceUsing N-body simulations with planet-disk interactions, we present a mechanism capable of forming compact systems of hot super Earths such as Kepler 11.
