Simulating Ionic Liquid Fragmentation in Electrospray Thrusters with Foundation Models
Ziyu Huang
Predicting the products of ionic-liquid impacts on extractor surfaces is important for electrospray-thruster lifetime analysis, yet available atomistic methods require a compromise…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Benchmarking Universal Machine Learning Force Fields for Molecular Dynamics of Lunar Regolith Minerals
Ziyu Huang, Ken-ichi Nomura
Universal machine-learning interatomic potentials provide a promising route for accelerating molecular dynamics simulations of materials, but their transferability to lunar regolit…
The Internal Nebular Attenuation Curve of Three-Dimensional Turbulent HII regions
Yifei Jin, Yong Shi, Ralph Sutherland +2
The internal dust attenuation of the Hii region reduces the observed emission-line fluxes. Turbulent density fields within each Hii region change the degree of the line-of-the-sigh…
Coupled Space Weathering: Nanophase Iron Formation by Micrometeoroid Impact and Solar Wind Sputtering
Ziyu Huang, Masatoshi Hirabayashi
Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulat…
First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c
Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30
We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We f…
Exoplanet Atmospheric Escape Observations with the Habitable Worlds Observatory
Leonardo A. Dos Santos, Eric D. Lopez, Luca Fossati +15
The Decadal Survey on Astronomy and Astrophysics 2020 highlights the importance of advancing research focused on discovering and characterizing habitable worlds. In line with this…
Surrogate Modeling of Landau Damping with Deep Operator Networks
Simin Shekarpaz, Chuanfei Dong, Ziyu Huang
Kinetic simulations excel at capturing microscale plasma physics phenomena with high accuracy, but their computational demands make them impractical for modeling large-scale space…
Machine-learning heat flux closure for multi-moment fluid modeling of nonlinear Landau damping
Ziyu Huang, Chuanfei Dong, Liang Wang
Nonlinear plasma physics problems are usually simulated through comprehensive modeling of phase space. The extreme computational cost of such simulations has motivated the developm…
Probing Cold-to-Temperate Exoplanetary Atmospheres: The Role of Water Condensation on Surface Identification with JWST
Ziyu Huang, Xinting Yu, Shang-Min Tsai +5
Understanding the surface temperature and interior structure of cold-to-temperate sub-Neptunes is critical for assessing their habitability, yet direct observations are challenging…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
