Trapping of giant-planet cores - I. Vortex aided trapping at the outer dead zone edge [PDF]

open access: yes, 2013
In this paper the migration of a 10 Earth-mass planetary core is investigated at the outer boundary of the dead zone of a protoplanetary disc by means of 2D hydrodynamic simulations done with the graphics processor unit version of the FARGO code.

Planetary Migration and Extrasolar Planets in the 2/1 Mean-Motion Resonance

open access: yes, 2004
We analyze the possible relationship between the current orbital elements fits of known exoplanets in the 2/1 mean-motion resonance and the expected orbital configuration due to migration.

Dead Zones as Thermal Barriers to Rapid Planetary Migration in Protoplanetary Disks

open access: yes, 2010
Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid ($\sim 10^5$ years) jeopardizing the existence of planetary systems.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets. II. The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model

open access: yesThe Astrophysical Journal
Although dust constitutes only about 1% of the mass in a protoplanetary disk, recent studies reveal its substantial impact on the torques experienced by low- and intermediate-mass planetary cores.

Diversity and Origin of 2:1 Orbital Resonances in Extrasolar Planetary Systems [PDF]

open access: yes, 2003
(Abridged) A diversity of 2:1 resonance configurations can be expected in extrasolar planetary systems, and their geometry can provide information about the origin of the resonances.

The Dynamical Interaction between Low-mass Planets and Dust Coagulation

open access: yesThe Astrophysical Journal Letters
We investigate the impact of a low-mass planet on dust coagulation, and its consequent feedback on planetary migration, using a linear analysis of the coupled dust–gas hydrodynamic equations.

The SOAPS project – Spin-orbit alignment of planetary systems

open access: yesEPJ Web of Conferences, 2013
The wealth of information rendered by Kepler planets and planet candidates is indispensable for statistically significant studies of distinct planet populations, in both single and multiple systems.

Diffusive Migration of Low-Mass Proto-planets in Turbulent Disks

open access: yes, 2006
Torque fluctuations due to magnetorotational turbulence in proto-planetary disks may greatly influence the migration patterns and survival probabilities of nascent planets.

On the Ordering of Exoplanet Systems

open access: yesThe Astrophysical Journal
We present a comprehensive analysis of planetary radius ordering within multiplanet systems, namely their ordinal position with respect to their size in a given system, utilizing data from the NASA Exoplanet Archive. In addition, we consider not only the
