Interplanetary shocks lacking type II radio bursts [PDF]

open access: yesThe Astrophysical Journal, 2010
We report on the radio-emission characteristics of 222 interplanetary (IP) shocks. A surprisingly large fraction of the IP shocks (~34%) is radio quiet (i.e., the shocks lacked type II radio bursts).

Ion‐Acoustic Waves Associated With Interplanetary Shocks

open access: yesGeophysical 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.

Interplanetary shock data base

open access: yesFrontiers 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 ...

In Situ Observation of Electron Acceleration by a Double Layer in the Bow Shock

open access: yesThe Astrophysical Journal, 2023
The importance of the electric potential along the field direction in the acceleration of electrons in the quasi-perpendicular bow shock has been proposed.

Particle Acceleration at Interplanetary Shocks [PDF]

open access: yesSpace 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.

Drift acceleration at interplanetary shocks [PDF]

open access: yesThe 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.

In situ local shock speed and transit shock speed [PDF]

open access: yesAnnales Geophysicae, 1998
A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Electrostatic Plasma Wave Excitations at the Interplanetary Shocks

open access: yesThe 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 ...

Signatures of interplanetary transients behind shocks and their associated near-surface solar activity [PDF]

open access: yesAnnales Geophysicae, 1998
Interplanetary transients with particular signatures different from the normal solar wind have been observed behind interplanetary shocks and also without shocks.

Scattering of Superthermal Ions at Shocks: Dependence on Energy

open access: yesThe Astrophysical Journal, 2023
Diffusive shock acceleration requires the production of backstreaming superthermal ions (injection) as a first step. Such ions can be generated in the process of scattering of ions in the superthermal tail off the shock front. Knowledge of the scattering
