A Study on Dust Dry Deposition: Wind-tunnel Experiment and Improved Parameterization [PDF]

, 2013
Dust deposition is a key component of the dust cycle in the Earth system. The lack of understanding for the mechanisms of dust deposition has been a major bottle neck to the development of the dust-related research field.

A New Method to Generate Dust with Astrophysical Properties [PDF]

, 2011
To model the size distribution and composition of interstellar and interplanetary dust grains, and their effect on a wide range of phenomena, it is vital to understand the mechanism of dust-shock interaction.

Seasonal and Diurnal Variability of Thermospheric Metastable Helium Observed by Multi‐Platform Observations and Numerical Modeling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Metastable helium (He∗ ${\text{He}}^{\ast }$) in the thermosphere emits at 1,083 nm and provides a powerful diagnostic of thermospheric composition, solar radiation, and transport. Its detection remains challenging because of its extremely low density and high‐altitude.

A Fast Second-order Solver for Stiff Multifluid Dust and Gas Hydrodynamics

The Astrophysical Journal Supplement Series
We present MDIRK: a multifluid second-order diagonally implicit Runge–Kutta method to study momentum transfer between gas and an arbitrary number ( N ) of dust species. The method integrates the equations of hydrodynamics with an implicit–explicit scheme

A new method to generate dust with astrophysical properties [PDF]

, 2010
In interstellar and interplanetary space, the size distribution and composition of dust grains play an important role. For example, dust grains determine optical and ultraviolet extinction levels in astronomical observations, dominate the cooling rate of

Laboratory astrophysics : investigation of planetary and astrophysical maser emission [PDF]

, 2013
This paper describes a model for cyclotron maser emission applicable to planetary auroral radio emission, the stars UV Ceti and CU Virginus, blazar jets and astrophysical shocks.

Particle-in-cell Simulations of Plasma Oscillations Excited by Dust Impacts

The Astrophysical Journal
Dust-impact-induced plasma oscillations (dust ringing) detected in Saturn’s Enceladus plume provide a novel method for measuring electron density. However, since S. Ye et al. discovered such events, their underlying mechanisms remain unclear.

Geometric Proca with matter in metric-Palatini gravity

European Physical Journal C: Particles and Fields, 2022
In the present work, we study linear, torsion-free metric-Palatini gravity, extended by the quadratics of the antisymmetric part of the Ricci tensor and extended also by the presence of the affine connection in the matter sector.

Optical Radiation Pressure: Resonant Mechanical Excitation of Thin Films

Annalen der Physik, Volume 538, Issue 10, October 2026.
The modulation of a laser beam generates a modulated radiation pressure force acting on a thin film. A resonant response is observed, leading to a net average thinning of the film. ABSTRACT Optical radiation pressure was directly observed for the first time more than a century ago.

A Detection of Circumgalactic Dust at Megaparsec Scales with Maximum Likelihood Estimation

The Astrophysical Journal
One of the more surprising astrophysical discoveries of the past decade has been the presence of enormous quantities of dust at megaparsec distances from galaxies, which has important implications for galaxy evolution, the circumgalactic and ...
