A Novel Blast Wave Solution for the Propagation of Coronal And Interplanetary Shocks

The Astrophysical Journal
Coronal mass ejections (CMEs) and their associated shock waves have severe space weather effects in the near-Earth space. Therefore, predicting the propagation and arrival time of the CME/shock is an important component of the space weather forecast.

The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data [PDF]

Geofísica Internacional, 2001
The angle θBn is the angle between the upstream magnetic field and the shock normal direction and is important for many phenomena in interplanetary physics.

Ion‐Acoustic Waves Associated With Interplanetary Shocks

Geophysical Research Letters
AbstractIon‐acoustic waves (IAWs) commonly occur near interplanetary (IP) shocks. These waves are important because of their potential role in the dissipation required for collisionless shocks to exist. We study IAW occurrence statistically at different heliocentric distances using Solar Orbiter to identify the processes responsible for IAW generation ...

Corotating drift-bounce resonance of plasmaspheric electron with poloidal ULF waves

Earth and Planetary Physics, 2017
The purpose of this paper is to understand how low energy plasmaspheric electrons respond to ULF waves excited by interplanetary shocks impinging on magnetosphere. It is found that both energy and pitch angle dispersed plasmaspheric electrons with energy

Automatic Identification of Interplanetary Shocks Based on Machine Learning

Space Weather
Fast forward interplanetary shocks (FFs) are one of the primary drivers of space weather events. This study presents an automated detection algorithm for FFs based on a multilayer perceptron model, utilizing in situ measurements of interplanetary ...

Variations of Heavy Ions in Different Types of Interplanetary Shocks

The Astrophysical Journal
Heavy ions upstream and downstream of interplanetary shocks are not only subject to acceleration, heating, and spatiotemporal modulation during their propagation in interplanetary space, but they can also, in turn, influence the dynamical properties of ...

Evidence for superdiffusive shock acceleration at interplanetary shock waves

Journal of Physics: Conference Series, 2015
Recent analysis of time profiles of energetic particles accelerated at interplanetary shocks has shown evidence for superdiffusive transport upstream of the shock fronts, namely for a transport characterized by a particle mean square displacement that grows faster than linearly in time.

Turbulence transport throughout the heliosphere

, 2007
We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Features of formation of small-scale wave disturbances during a sudden magnetospheric compression

Solar-Terrestrial Physics, 2017
Quasi-periodic changes of the geomagnetic field and plasma parameters in the range of Pc 5 pulsations, which occurred immediately after the interaction of interplanetary shock (IPS) with Earth’s magnetosphere in the event of April 24, 2009 at 00:53 UT ...
