Circumplanetary Disks are Rare Around Planets at Large Orbital Radii: A Parameter Survey of Flow Morphology Around Giant Planets

The Astrophysical Journal
We investigate how the formation and structure of circumplanetary disks (CPDs) vary with planet mass and protoplanetary disk aspect ratio. Using static mesh refinement and a near-isothermal equation of state, we perform a small parameter survey of ...

Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures

Advanced Robotics Research, EarlyView.
A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

The JWST/NIRISS Deep Spectroscopic Survey for Young Brown Dwarfs and Free-floating Planets

The Astronomical Journal
The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. Here we report results from an extremely deep spectroscopic survey of the young star cluster NGC1333 ...

Enhancing the Mechanical Properties of Inherently Brittle, Biobased and Biodegradable Polyhydroxybutyrate (PHB) Polymer by Cotton Fibre Reinforcement and Interfacial Grafting

Advanced Sustainable Systems, EarlyView.
This study enhances biobassed, biodegradable polyhydroxybutyrate (PHB)s strength and ductility by reinforcing it with polyvinyl alcohol (PVA)‐coated cotton fibres and further improving interfacial bonding through maleic anhydride (MA) grafting. In addition to mechanical performance, the approaches significantly improve the gas barrier properties of the

Influence of Orbit and Mass Constraints on Reflected Light Characterization of Directly Imaged Rocky Exoplanets

The Astrophysical Journal Letters
Survey strategies for upcoming exoplanet direct imaging missions have considered varying assumptions of prior knowledge. Precursor radial velocity surveys could have detected nearby exo-Earths and provided prior orbit and mass constraints. Alternatively,

Unveiling the Capacity Boosting Mechanism of the MoS2 Electrode by Focusing on the Under Potential Deposition in All‐Solid‐State Batteries Prepared by One‐Pot One‐Step Liquid Phase Mixing

Advanced Sustainable Systems, EarlyView.
MoS2 electrodes with high dispersion for solid‐state rechargeable batteries is successfully fabricated by using one‐pot one‐step liquid‐phase mixing methods, which realize exfoliating MoS2, synthesizing solid electrolytes, and compositing with conductive agents in a single step. And underpotentially deposited lithium metal is observed onto the metallic

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-dependent Variability Driven by Multiple Mechanisms

The Astrophysical Journal Letters
Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate their heat from formation as they cool, primarily at infrared wavelengths ...

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design
