arXiv, 2010 Planet migration is the process by which a planet's orbital radius changes in time. The main agent for causing gas giant planet migration is the gravitational interaction of the young planet with the gaseous disk from which it forms. We describe the migration rates resulting from these interactions based on a simple model for disk properties.

Fast migration of low-mass planets in radiative discs [PDF]
, 2015 Low-mass planets are known to undergo Type I migration and this process must have played a key role during the evolution of planetary systems. Analytical formulae for the disc torque have been derived assuming that the planet evolves on a fixed circular orbit.

Modulation of NH2‐UiO‐66 Based MOFs for Gas Phase CO2 Photocatalytic Reduction
Advanced Energy Materials, EarlyView.This study addresses the dual challenges of the greenhouse effect and energy crisis through the direct capture and conversion of CO2 using Metal‐Organic Frameworks (MOFs). By synthesizing defective NH2‐UiO‐66 MOFs and combining them with TiO2 and gold nanoparticles, a ternary photocatalyst that significantly enhances CO2 adsorption and CH4 production ...

Solar System Migration Points to a Renewed Concept: Galactic Habitable Orbits
The Astrophysical Journal LettersAstrophysical 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.

Revealing signatures of planets migrating in protoplanetary discs with ALMA multi-wavelength observations [PDF]
, 2019 Recent observations show that rings and gaps are ubiquitous in protoplanetary discs. These features are often interpreted as being due to the presence of planets; however, the effect of planetary migration on the observed morphology has not been investigated hitherto.

Radial migration of gap-opening planets in protoplanetary disks. I. The case of a single planet [PDF]
, 2018 A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk-planet interaction and migrates with the gap in the disk. It is expected that in the ideal case, a gap-opening planet migrates at the viscous drift speed, which is referred to as type II migration.
