12CO Ro-Vibrational Spectroscopy of Protoplanetary Disks: Inferring Planet-Disk Interactions [PDF]

Observing and studying planets around young stars during their initial formation stages is essential for understanding the physics of their formation. Protoplanetary disks are the host sites of planets, and they exhibit substructures that hint towards ...

Gaps and rings: a near-universal trait of extended protoplanetary discs

Astronomy & Astrophysics
Context. Substructures such as rings, gaps, and cavities are commonly observed in protoplanetary discs and are thought to play a key role in dust evolution and planet formation.

Nickel‐Catalyzed LiF‐Rich Interface for Silicon Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Modulating the decomposition of F‐containing species in the electrolyte to form LiF‐rich SEI has been proven to be an effective strategy for interface optimization. Herein, through nickel‐catalyzed pyrolysis of carbon precursors on silicon, graphene‐like carbon was formed to construct three‐dimensional conductive networks.

exoALMA. XVII. Characterizing the Gas Dynamics around Dust Asymmetries

The Astrophysical Journal Letters
The key planet-formation processes in protoplanetary disks remain an active matter of research. One promising mechanism to radially and azimuthally trap millimeter-emitting dust grains, enabling them to concentrate and grow into planetesimals, is ...

Visualizing the kinematics of planet formation [PDF]

, 2020
A stunning range of substructures in the dust of protoplanetary disks is routinely observed across a range of wavelengths. These gaps, rings and spirals are highly indicative of a population of unseen planets, hinting at the possibility of current ...

A multi-fluid approach for polydisperse pebble accretion

Astronomy & Astrophysics
Context. Pebble accretion offers an efficient pathway to form planets, driven by a constant supply of inward drifting mass and an accretion efficiency enhanced by gas drag. While most studies assume a single pebble size (monodisperse), real discs contain

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Planet formation, orbital evolution and planet-star tidal interaction [PDF]

, 1998
We consider several processes operating during the late stages of planet formation that can affect observed orbital elements. Disk-planet interactions, tidal interactions with the central star, long term orbital instability and the Kozai mechanism are ...
