Discrete stochastic charging of aggregate grains
(Physical Review E, 2018-05)
Dust particles immersed in a plasma environment become charged through the collection of electrons and ions at random times, causing the dust charge to fluctuate about an equilibrium value. Small grains (with radii less ...
Effect of Dipole-Dipole Charge Interactions on Dust Coagulation
(New Journal of Physics, 2009-06-16)
This study examines the effect that dipole–dipole charge interactions
between fractal aggregates have on the growth of dust grains. Aggregates in a
plasma or radiative environment will have charge distributed over their ...
How to make large, void-free dust clusters in dusty
(IOP publishing, 2008-12-18)
Collections of micrometer-sized solid particles immersed in plasma
are used to mimic many systems from solid state and fluid physics, due to their
strong electrostatic interaction, their large inertia, and the fact that ...
Numerical study of anomalous diffusion of light in semi-crystalline polymer structures
(American Physical Society, 2020-12)
From the spread of pollutants in the atmosphere to the transmission of nutrients across cell membranes, anomalous diffusion processes are ubiquitous in natural systems. The ability to understand and control the mechanisms ...
Branes in the M_D x M_d+ x M_d- Compactification of Type II String on S^1/Z_2 and Their Cosmologicval Applications
(2010-07-09)
In this paper, we study the implementation of brane worlds in type II string theory. Starting with the NS/NS sector of type II string, we first compactify the (D + d+ + d−)-dimensional spacetime, and reduce the corresponding ...
The magnetic field inside a protoplanetary disk gap opened by planets of different masses
(Monthly Notices of the Royal Astronomical Society, 2017)
We perform magnetohydrodynamic simulations of protoplanetary disc gaps opened by planets
of various masses, with the aim of calculating the strength of the vertical magnetic field
threading such gaps. We introduce a ...
Coagulation in the Vicinity of a Gap-Opening Jupiter-Mass Planet
(Astrophysical Journal, 2016-06)
We analyze the coagulation of dust in and around a gap opened by a Jupiter-mass planet. To this end, we carry out a high-resolution magnetohydrodynamic (MHD) simulation of the gap environment, which is turbulent due to the ...
The influence of monomer shape on aggregate morphologies
(Astronomy & Astrophysics, 2012-03)
Context. The coagulation of dust particles is the initial step in planetary formation, with the precursors to planetesimals believed to form via the collisions of micron and submicron sized dust particles in the disk ...
Charging and Growth of Fractal Dust Grains
(IEEE Transactions on Plasma Science, 2008-02)
The structure and evolution of aggregate grains formed within a plasma environment are dependent on the charge acquired by the micron-sized dust grains during the coagulation process. The manner in which the charge is ...
Charged Grains In Saturn's F-Ring: Interaction With Saturn's Magnetic Field
(Advances in Space Research, 2004)
Saturn’s dynamic F-Ring still presents a challenge for understanding and explaining the kinematic processes that lead to the changing structure visible in our observations of this ring. This study examines the effect of ...
