Interplanetary circumstances of quasi‐perpendicular interplanetary shocks in 1996–2005 [PDF]

Journal of Geophysical Research, 2010
The angle (θBn) between the normal to an interplanetary shock front and the upstream magnetic field direction, though often thought of as a property “of the shock,” is also determined by the configuration of the magnetic field immediately upstream of the shock. We investigate the interplanetary circumstances of 105 near‐Earth quasi‐perpendicular shocks

Ion‐Acoustic Waves Associated With Interplanetary Shocks [PDF]

Geophysical Research Letters
Ion‐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.

Particle Acceleration at Interplanetary Shocks [PDF]

Space Science Reviews, 2007
This paper briefly reviews proton acceleration at interplanetary shocks. This is key to describing the acceleration of heavy ions at interplanetary shocks because wave excitation—and hence particle scattering—at oblique shocks is controlled by the protons and not the heavy ions.

Storm Sudden Commencements Without Interplanetary Shocks [PDF]

Journal of Astronomy and Space Sciences, 2015
Storm sudden commencements (SSCs) occur due to a rapid compression of the Earth's magnetic field. This is generally believed to be caused by interplanetary (IP) shocks, but with exceptions. In this paper we explore possible causes of SSCs other than IP

Electrostatic Plasma Wave Excitations at the Interplanetary Shocks

The Astrophysical Journal, 2023
Over the last few decades, different types of plasma waves (e.g., the ion acoustic waves (IAWs), electrostatic solitary waves, upper/lower hybrid waves, and Langmuir waves) have been observed in the upstream, downstream, and ramp regions of the ...

On the Speed of Interplanetary Shocks Propagating through the Magnetosheath

, 2023
International audienceInterplanetary shocks are some of the main drivers of geomagnetic storms. Before they can impact the geomagnetic environment, they propagate through the magnetosheath where their properties and geometry can be modified.

On the role of interplanetary shocks in accelerating MeV electrons

Astronomy & Astrophysics, 2023
Context. One of the sources of solar energetic particle (SEP) events is shocks that are driven by fast coronal mass ejections (CMEs). They can accelerate SEPs up to relativistic energies and are attributed to the largest SEP events. New studies suggest that CME-driven shocks can potentially accelerate electrons to MeV energies in the vicinity of the ...

Compression of the Earth's magnetotail by interplanetary shocks directly drives transient magnetic flux closure [PDF]

, 2006
We use a novel method to evaluate the global opening and closure of magnetic flux in the terrestrial system, and to analyse two interplanetary shock passages that occurred during magnetically quiet periods. We find that, even under these quiet conditions,

Interplanetary shock data base

Frontiers in Astronomy and Space Sciences, 2023
In this manuscript, I provide an updated interplanetary shock data base I published in previous works. This list has now 603 events. I also present and describe the data and methodologies used to compile this list. The main contribution of this work is to provide an updated end accurate interplanetary shock data base for future space physics and space ...

Drift acceleration at interplanetary shocks [PDF]

The Astrophysical Journal Supplement Series, 1994
AbstractScatter-free acceleration of energetic particles by quasi-perpendicular interplanetary shocks is investigated. A brief review is given on the predictions of the gradient drift acceleration model concerning the energy, time, and angular dependence of the particle flux caused by a single shock encounter interaction.
