Time-variability in the Interstellar Boundary Conditions of the Heliosphere over the past 60,000 years: Impact of the Solar Journey on the Galactic Cosmic Ray Flux at Earth
Time-variability the Interstellar Boundary Conditions
2011/1/10
During the solar journey through galactic space, variations in the physical properties of the surrounding interstellar material (ISM) modify the heliosphere and modulate the flux of galactic cosmic ra...
Transient Perturbations and their Effects in the Heliosphere, the Geomagnetosphere, and the Earth’s Atmosphere: Space Weather Perspective
Space weather geomagnetic storm cosmic ray Forbush decrease interplanetary shock coronal mass ejection
2010/9/16
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth’s atmosphere. In particular, transient perturbations in solar wind plas...
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...
Small-scale Alfvènic turbulence in the outer heliosphere is mainly determined by a source which is connected with the instability of the initially highly anisotropic velocity distribution of interstel...
MHD modeling of the Heliosphere：a critical evaluation of different models
Heliosphere critical evaluation
2009/5/27
The very complicated problem of the solar wind-interstellar medium interaction requires a very sophisticated numerical approach. To achieve such a goal first we need to understand very deeply the resu...
Observations of anomalous transport of energetic electrons in the heliosphere
energetic electrons anomalous transport heliosphere
2009/5/27
We study the propagation of energetic particles, accelerated by interplanetary shock waves, upstream of the shock, considering the possibility of having anomalous transport. The theoretical treatment ...
On the validity of ideal MHD in the vicinity of stagnation points in the heliosphere and other astrospheres
heliospheric boundaries magnetic fields stagnation points
2009/5/27
The paradigm of ideal MHD is investigated in the vicinity of null points of flows and magnetic fields. These null points determine the location and geometrical shape of the heliopause (or other astrop...
