Making systems of Super Earths by inward migration of planetary embryos [PDF]

, 2013
Using N-body simulations with planet-disk interactions, we present a mechanism capable of forming compact systems of hot super Earths such as Kepler 11. Recent studies show that outward migration is common in the inner parts of radiative disks. However we show that two processes naturally tip the balance in favor of inward migration.

Mechanophysical Synthesis of Core/Shell Hybrid Supraparticles

Advanced Materials, EarlyView.
Collision‐driven mechanophysical synthesis enables rapid, chemical‐free assembly of core/shell hybrid supraparticles (HSPs) by embedding inorganic nanomaterials onto polymer microparticles. Governed by collision and interfacial energies, this scalable, solvent‐free method accommodates diverse material combinations, allowing multifunctional HSPs for ...

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 ...

Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

Advanced Materials Technologies, EarlyView.
Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies are employed to stabilize SnO2 upon cycling i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating.

Canadian contributions to environmetrics

Canadian Journal of Statistics, Volume 50, Issue 4, Page 1355-1386, December 2022., 2022
Abstract This article focuses on the importance of collaboration in statistics by Canadian researchers and highlights the contributions that Canadian statisticians have made to many research areas in environmetrics. We provide a discussion about different vehicles that have been developed for collaboration by Canadians in the environmetrics context as ...

From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance

Advanced Optical Materials, EarlyView.
Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings

Streaming Torque with Turbulent Diffusion

The Astrophysical Journal
Fast type I migration of (proto)planets poses a challenging problem for the core accretion formation scenario. We found that the dust-induced “Streaming Torque” (ST) may slow down or even reverse the planet migration in Q. Hou & C. Yu.

Interlíngua: miscigenação linguística e ficção poética

MatLit, 2015
This article addresses the issue of inter-language in the contemporary situation, a process of relationship among languages, caused mostly by mobility, migration, nomadism, war, globalization, colonization, exile and, more recently, digital ...

High-contrast Imaging around a 2 Myr-old CI Tau with a Close-in Gas Giant

The Astronomical Journal, 2022
Giant planets around young stars serve as a clue to unveiling their formation history and orbital evolution. CI Tau is a 2 Myr-old classical T Tauri star hosting an eccentric hot Jupiter, CI Tau b.

Probing the impact of varied migration and gas accretion rates for the formation of giant planets in the pebble accretion scenario [PDF]

, 2020
The final orbital position of growing planets is determined by their migration speed, which is essentially set by the planetary mass. Small mass planets migrate in type I migration, while more massive planets migrate in type II migration, which is thought to depend mostly on the viscous evolution rate of the disc.
