Origin of the Asymmetric Gas Distribution near the Co-orbital Lagrange Points of an Embedded Planet

The Astrophysical Journal
Hydrodynamic simulations of planet–disk interactions often show material accumulation near the co-orbital Lagrange points L _4 and L _5 —features that may correspond to observed crescents in protoplanetary disks. Intriguingly, these simulations also show

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet’s Orbital Eccentricity

The Astrophysical Journal
Eccentric planets constitute a large population of the known exoplanets and may drive significant substructures in protoplanetary disks through planet–disk interactions if their eccentricities are excited early in the planet formation process.

Topics on Planet-Disk Interaction and Solar Convection

, 2019
In this thesis I focus on two topics: planet-disk interaction and solar convection. These two seemingly separate topics are connected via a similar separation of timescales. Planets excite spiral waves in their disks on fast timescales compared to the time for the disk to viscously adjust to the angular momentum deposited by those waves.

Planet-Disk Interactions and Early Evolution of Planetary Systems [PDF]

, 2014
The great diversity of extrasolar planetary systems has challenged our understanding of how planets form, and how their orbits evolve as they form. Among the various processes that may account for this diversity, the gravitational interaction between planets and their parent protoplanetary disc plays a prominent role in shaping young planetary systems.

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

Carbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

3D-radiation hydro simulations of disk-planet interactions. I. Numerical algorithm and test cases [PDF]

, 2005
We study the evolution of an embedded protoplanet in a circumstellar disk using the 3D-Radiation Hydro code TRAMP, and treat the thermodynamics of the gas properly in three dimensions.

Suppression of Resonant Overstability at Sharp Migration Gradients

The Astrophysical Journal
Mean-motion resonances are expected to frequently arise at the inner edges of protoplanetary disks, where planet–disk interactions facilitate large-scale orbital convergence.

Kirkendall‐Effect‐Mediated Hollow Bimetallic Hexacyanoferrates for Aqueous Zn‐Ion Batteries: Suppressing Jahn–Teller Distortions and Enhancing Ion Transport and Cyclability

Carbon Energy, EarlyView.
Kirkendall‐engineered hollow Ni–Mn hexacyanoferrates feature Ni‐tunable shell thickness and uniform alloying, coupling architectural control with electronic stabilization. Composition–morphology co‐optimization suppresses Mn³⁺‐driven Jahn–Teller distortions and lowers charge‐transfer barriers, enabling rapid Zn²⁺ transport and reversible redox.
