Parker Solar Probe Observations of Turbulence and Waves between a Current Sheet and an Interplanetary Coronal Mass Ejection–Driven Shock

The Astrophysical Journal
We report on unusual magnetic wave activity seen in a region between the crossing of a current sheet and an interplanetary shock by the Parker Solar Probe (PSP).

Evolution of the Suprathermal Proton Population at Interplanetary Shocks [PDF]

, 2019
We investigate the evolution of the suprathermal (ST) proton population as interplanetary shocks cross 1 au. The variability of the ST proton intensities and energy spectra upstream of the shocks is analyzed in terms of the shock parameters, upstream ...

The Radiation, Interplanetary Shocks, and Coronal Sources (RISCS) Toolset [PDF]

, 2014
The goal of this project is to serve the needs of space system designers and operators by developing an interplanetary radiation environment model within 10 AU:Radiation, Interplanetary Shocks, and Coronal Sources (RISCS) toolset: (1) The RISCS toolset ...

Multiple spacecraft observations of interplanetary shocks: Characteristics of the upstream ULF turbulence [PDF]

, 1982
All interplanetary shocks observed by ISEE-3 and either ISEE-1 or ISEE-2 or both in 1978 and 1979 are examined for evidence of upstream waves. In order to characterize the properties of these shocks it is necessary to determine accurate shock normals. An

Similarities and Differences between ICME-driven Shocks Observed by VEX (∼0.72 au) and WIND (∼1.0 au)

The Astrophysical Journal
The features of interplanetary shocks driven by interplanetary coronal mass ejections (ICMEs) observed by WIND (∼1.0 au) and Venus Express (VEX; ∼0.72 au) during the same period are statistically analyzed by comparing their similarities and differences ...

Electron heating at interplanetary shocks [PDF]

, 1982
Data for 41 forward interplanetary shocks show that the ratio of downstream to upstream electron temperatures. T sub e (d/u) is variable in the range between 1.0 (isothermal) and 3.0.

Acceleration Of ³He Nuclei At Interplanetary Shocks

, 2001
We have surveyed the 0.5-2.0 MeV nucleonˉ¹ ion composition of 56 interplanetary (IP) shocks observed with the Ultra - Low-Energy Isotope Spectrometer on board the Advanced Composition Explorer from 1997 October 1 through 2000 November 30.

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 ...

Search Coil vs. Fluxgate Magnetometer Measurements at Interplanetary Shocks [PDF]

, 2012
We present magnetic field observations at interplanetary shocks comparing two different sample rates showing significantly different results. Fluxgate magnetometer measurements show relatively laminar supercritical shock transitions at roughly 11 samples/
