Electron heating at interplanetary shocks
, 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.

Automatic Identification of Interplanetary Shocks Based on Machine Learning
Space WeatherFast 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 ...

Particle acceleration at shocks and magnetic turbulence in the interplanetary space
, 2019 Dottorato Ricerca in Scienze e Tecnologie Fisiche, Chimiche e dei Materiali. Ciclo XXXIThe solar wind is a supersonic and super-alfvenic flow of plasma that propagates in space up to the Earth and throughout the heliosphere reaching speeds of about 400

Associations between coronal mass ejections and interplanetary shocks
, 1983 Nearly continuous complementary coronal observations and interplanetary plasma measurements for the years 1979-1982 are compared. It is shown that almost all low latitude high speed coronal mass ejections (CME's) were associated with shocks at HELIOS 1 ...

Evolution of the Suprathermal Proton Population at Interplanetary Shocks
, 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 ...

Search Coil vs. Fluxgate Magnetometer Measurements at Interplanetary Shocks
, 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/

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 ...

, 2011 Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...

Candidates for downstream jets at interplanetary shocks [PDF]
Localized dynamic pressure enhancements arising from kinetic processes are frequently observed downstream of the Earth’s bow shock. These structures, called jets, modify their plasma surroundings and participate in particle energization.

Interplanetary Shocks and "Suprathermal" Flare Particles
, 2006 We use ion-composition data from ACE/ULEIS, low energy electrons from ACE/EPAM, high energy protons from SoHO/ERNE, radio data from Wind/WAVES, and solar wind data from ACE/SWEPAM and ACE/MAG to investigate the solar and interplanetary circumstances near
