Solar System Migration Points to a Renewed Concept: Galactic Habitable Orbits

The Astrophysical Journal Letters
Astrophysical evidence suggests that the Sun was born near 5 kpc from the Galactic center, within the corotation radius of the Galactic bar, around 6–7 kpc.

Recent developments in planet migration theory

, 2012
Planetary migration is the process by which a forming planet undergoes a drift of its semi-major axis caused by the tidal interaction with its parent protoplanetary disc.

Influence of Modeling Assumptions on the Inferred Dynamical State of Resonant Systems: A Case Study of the HD 45364 System

The Astrophysical Journal
Planetary systems exhibiting mean motion resonances (MMRs) offer unique opportunities to study the imprint of disk-induced migration on the orbital architectures of planetary systems. The HD 45364 system, discovered via the radial velocity (RV) method to

Dead Zones and the Diversity of Exoplanetary Systems

, 2011
Planetary migration provides a theoretical basis for the observed diversity of exoplanetary systems. We demonstrate that dust settling - an inescapable feature of disk evolution - gives even more rapid type I migration by up to a factor of about 2 than ...

Narrative, Scale, and Two Refugee Crises in Comparison in Italian Media

Diegesis: Interdisziplinäres E-Journal für Erzählforschung, 2023
Bringing together narrative theory, migration studies, and contemporary discussions in the environmental humanities, this article considers the significance of the concept of scale for media narratives on migration.

Formation, migration, and stability of extrasolar planetary systems [PDF]

Proceedings of the International Astronomical Union, 2004
This paper presents recent results concerning the planet formation, planet migration, and the long term stability of planetary systems. Most stars are found in binary systems and binary companions can disrupt both planet formation and stability. We first consider the effects of outer binary companions on the late stages of terrestrial planet formation ...
