A numerical model of cohesion in planetary rings
Planetary rings Saturn, Rings Rotational dynamics Tides, Solid body Ices, Mechanical properties Collisional physics
2015/12/25
We present a numerical method that incorporates particle sticking in simulations using the N-body code pkdgrav to study motions in a local rotating frame, such as a patch of a planetary ring. Particle...
A steady-state model of NEA binaries formed by tidal disruption of gravitational aggregates
Asteroids dynamics Satellites of asteroids
2015/12/25
We present results of a simulation of a steady-state binary near-Earth asteroid (NEA) population. This study combines previous work on tidal disruption of gravitational aggregates [Walsh, K.J., Richar...
Binary near-Earth asteroid formation:Rubble pile model of tidal disruptions
Asteroids Dynamics Rotational dynamics Tides solid body
2015/12/25
We present numerical simulations of near-Earth asteroid (NEA) tidal disruption resulting in bound, mutually orbiting systems. Using a rubble pile model we have constrained the relative likelihoods for...
Dynamical Opacity-Sampling Models of Mira Variables. II: Time-Dependent Atmospheric Structure and Observable Properties of 4 M-Type Model Series
stars: AGB and post-AGB, stars: atmospheres, stars: variables: other, stars: mass loss
2011/10/11
We present 4 model series of the CODEX dynamical opacity-sampling models of Mira variables with solar abundances, designed to have parameters similar to $o$ Cet, R Leo and R Cas. We demonstrate that t...
A Model for the Origin of High Density in Loop-top X-ray Sources
Model Origin Density Loop-top X-ray Sources
2011/10/8
Super-hot looptop sources, detected in some large solar flares, are compact sources of HXR emission with spectra matching thermal electron populations exceeding 30 megakelvins. High observed emission ...
Excursion Set Halo Mass Function and Bias in a Stochastic Barrier Model of Ellipsoidal Collapse
Excursion Set Function Stochastic Barrier Model Ellipsoidal Collapse
2011/9/29
We use the Excursion Set formalism to compute the properties of the halo mass distribution for a stochastic barrier model which encapsulates the main features of the ellipsoidal collapse of dark matte...
Magnetosonic Waveguide Model of Solar Wind Flow Tubes
Solar wind MHD waves magnetic flux tubes
2010/9/17
We consider solar wind flow tubes as a magnetosonic waveguide.Assuming a symmetric expansion in edges of slab-modelled waveguide,we study the propagation characteristics of magnetosonic wave in the so...
Helicity of Solar Active Regions from a Dynamo Model
MHD—Sun activity—Sun magnetic fields—sunspots
2010/9/16
We calculate helicities of solar active regions based on the idea that poloidal flux lines get wrapped around a toroidal flux tube rising through the convection zone, thereby giving rise to the helici...

A Simple Model for Reflection-Driven Spectral Evolution of Turbulence in the Corona and Inner Heliosphere
Inner Heliosphere Corona Reflection-Driven Spectral Evolution
2009/5/27
Dissipation of turbulence is generally considered as a prime candidate for the heating and acceleration of solar wind from the corona throughout the heliosphere, due to radially evolving dissipation p...
