Migration of the outermost objects in planetary systems [PDF]

EAS Publications Series, 2010
The outermost bodies of planetary systems embedded in a planetesimal disk migrate much faster than the other planets. The outward migration of such bodies is self-sustained by supplying fresh planetesimals up to the edge of the disk. We study the dynamics of gravitational interactions between an outer planet and massive planetesimals during this ...

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.

Electric Field Driven Soft Morphing Matter

Advanced Materials, EarlyView.
This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...

Towards a More Just Canadian Education-migration System: International Student Mobility in Crisis

Studies in Social Justice, 2022
Education-migration, or the multi-step recruitment and retention of international students as immigrants, is an increasingly important component of both higher education and so-called highly-skilled migration.

Toward Stable, High‐Energy, Partially Disordered Mn‐Rich Spinel Cathodes by Revealing and Mitigating Surface Degradation

Advanced Materials, EarlyView.
Mechano‐activated partially disordered spinel LiMn2O4 is demonstrated with high Mn utilization and a specific energy over 800 Wh kg−1 at the cathode active material (CAM) level. Surface degradation, caused by the Jahn‐Teller effect in baseline commercial carbonate electrolyte (Gen 2), intensifies Mn2+ dissolution and crosstalk at high potentials ...

Density Waves Excited by Low-Mass Planets in Protoplanetary Disks I: Linear Regime

, 2011
Density waves excited by planets embedded in protoplanetary disks play a central role in planetary migration and gap opening processes. We carry out 2D shearing sheet simulations to study the linear regime of wave evolution with the grid-based code ...

Effects of Interfacial Adhesion on Lithium Plating Location in Solid‐State Batteries with Carbon Interlayers

Advanced Materials, Volume 37, Issue 29, July 24, 2025.
Carbon interlayers can promote the stable cycling of anode‐free solid‐state batteries, but their underlying mechanisms have remained elusive. In this study, a direct correlation is observed between the interfacial adhesion of the carbon interlayer and the location of lithium plating.

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Nitrogen Loss from Pluto’s Birth to the Present Day via Atmospheric Escape, Photochemical Destruction, and Impact Erosion

The Planetary Science Journal
We estimate the loss of nitrogen from Pluto over its lifetime, including the giant planet instability period, which we term the “Wild Years.” We analyze the orbital migration of 53 simulated Plutinos, which are Kuiper Belt Objects (KBOs) captured into 3 ...
