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

On Wave Interference in Planet Migration: Dead Zone Torques Modified by Active Zone Forcing
The Astrophysical Journal, 2023 We investigate planetary migration in the dead zone of a protoplanetary disk where there is a set of spiral waves propagating inward due to the turbulence in the active zone and the Rossby wave instability, which occurs at the transition between the dead

, 2008 Gravitational torques between a planet and gas in the protoplanetary disk result in orbital migration of the planet, and are likely to play an important role in the formation and early evolution of planetary systems. For masses comparable to those of observed giant extrasolar planets, the interaction with the disk is strong enough to form a gap ...

Evolution of planetesimal discs and planetary migration [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 In this paper, we further develop the model for the migration of planets introduced in Del Popolo, Gambera and Ercan, and extended to time-dependent planetesimal accretion disks in Del Popolo and Eksi. More precisely, the assumption of Del Popolo and Eksi that the surface density in planetesimals is proportional to that of gas is released.

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

Orbital Migration Models under Test
, 2010 Planet-disk interaction predicts a change in the orbital elements of an embedded planet. Through linear and fully hydrodynamical studies it has been found that migration is typically directed inwards.

Stability and Formation of the Resonant System HD 73526 [PDF]
, 2007 Based on radial velocity measurements it has been found recently that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as our numerical integration shows, the derived orbital data for this system result in chaotic ...

TOI-1333Ab is on a well-aligned orbit
Astronomy & AstrophysicsContext. Spin-orbit obliquity measurements of hot-Jupiter systems constrain giant planet migration and tidal evolution. In binary systems, combining stellar obliquities with the orbit-orbit angle (γ) between the planetary and stellar companion orbits ...
