Percolative sulfide core formation in oxidized planetary bodies [PDF]
Models of planetary core formation traditionally involve the fractionation of Fe,Ni-metal melts from silicate mantles after extensive silicate melting.

A torque formula for non-isothermal type I planetary migration – I. Unsaturated horseshoe drag [PDF]
We study the torque on low-mass planets embedded in protoplanetary discs in the two-dimensional approximation, incorporating non-isothermal eects. We couple linear estimates of the Lindblad (or wave) torque to a simple, but non-linear, model of adiabatic

Effects of the planetary migration on some primordial satellites of the outer planets - I. Uranus’ case [PDF]
Context. During the first hundred million years after the formation of our solar system, the four giant planets are believed to have migrated significantly (by up ≈20 AU).

The capture of Trojan asteroids by the giant planets during planetary migration [PDF]
Of the four giant planets in the Solar system, only Jupiter and Neptune are currently known to possess swarms of Trojan asteroids - small objects that experience a 1:1 mean motion resonance with their host planet.

DEAD ZONES AS THERMAL BARRIERS TO RAPID PLANETARY MIGRATION IN PROTOPLANETARY DISKS [PDF]
Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid (∼105 years), jeopardizing the existence of planetary systems.

Migration-Induced Architectures of Planetary Systems [PDF]
The recent increase in number of known multi-planet systems gives a unique opportunity to study the processes responsible for planetary formation and evolution. Special attention is given to the occurrence of mean-motion resonances, because they carry important information about the history of the planetary systems. At the early stages of the evolution,

Planetary Migration and Plutino Orbital Inclinations [PDF]
I investigate which mechanisms could have acted during Neptune's past radial migration to excite plutino orbital inclinations to their present values. These processes include Kozai resonance and the ν18 secular resonance, both before and after the plutino's capture into the 2 : 3 mean motion resonance with Neptune. In the case that ν18 acted before the

Planet heating prevents inward migration of planetary cores [PDF]
Planetary systems are born in the disks of gas, dust and rocky fragments that surround newly formed stars. Solid content assembles into ever-larger rocky fragments that eventually become planetary embryos.

TILTING JUPITER (A BIT) AND SATURN (A LOT) DURING PLANETARY MIGRATION [PDF]
We study the effects of planetary late migration on the gas giants’ obliquities. We consider the planetary instability models from Nesvorný and Morbidelli, in which the obliquities of Jupiter and Saturn can be excited when spin–orbit resonances occur ...
