Numerical simulations of type III planetary migration â II. Inward migration of massive planets [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We present a numerical study of rapid, so called type III migration for Jupiter-sized planets embedded in a protoplanetary disc. We limit ourselves to the case of outward migration, and study in detail its evolution and physics, concentrating on the structure of the co-rotation and circumplanetary regions, and processes for stopping migration.

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Planet–Planet Secular Migration Predicts a Stellar Obliquity–Period Anticorrelation
The Astrophysical Journal LettersStellar obliquities provide a fossil record of hot-Jupiter (HJ) migration. An emerging observational trend in single-star systems is that strongly misaligned HJs are largely confined to short orbital periods, while longer-period HJs are preferentially ...

Enhanced Size Uniformity for Near-resonant Planets
The Astrophysical Journal, 2023 Super-Earths within the same close-in, compact planetary system tend to exhibit a striking degree of uniformity in their radius, mass, and orbital spacing, and this “peas-in-a-pod” phenomenon itself serves to provide one of the strongest constrains on ...

Building bridges for migration in a planetary context [PDF]
European Journal of Public Health, 2019 Abstract Europe is experiencing high volumes of migration, both within and to the region. Globally, several factors contributing to high-volume migration, ranging from economic ones (migrant workers) to forced displacement caused by conflict, persecution and climate changes (draught or other extreme ...

Advanced Science, EarlyView.A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...
