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.

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 ...

Evolution of Electron Acceleration by Corotating Interaction Region Shocks at 1 au

The Astrophysical Journal Letters
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse)

Proton Temperature Anisotropy across Interplanetary Shocks: A Statistical Analysis with WIND Observations

The Astrophysical Journal Letters
Interplanetary (IP) shocks efficiently modify the proton temperature anisotropy of the solar wind. Analyzing ∼800 IP shocks observed by the Wind spacecraft from 1997 to 2024, we present a statistical study of upstream and downstream proton temperature ...
