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.

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.

Variation of the Interplanetary Shocks in the Inner Heliosphere
, 2021 Observations of the solar wind plasma and interplanetary magnetic field in the ecliptic plane by the Voyager 1 and 2 spacecraft are utilized to study the variation of the interplanetary shocks (with magnetosonic Mach number >1) encountered in the inner ...

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

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

Electron Energy Partition across Interplanetary Shocks. II. Statistics [PDF]
Astrophysical Journal Supplement Series, 2019 A statistical analysis of 15,210 electron velocity distribution function (VDF) fits, observed within ±2 hr of 52 interplanetary (IP) shocks by the Wind spacecraft near 1 au, is presented. This is the second in a three-part series on electron VDFs near IP

CLASSIFICATION OF THE INTERPLANETARY SHOCKS BY SHOCK DRIVERS [PDF]
Journal of The Korean Astronomical Society, 2002 From the data of solar wind observation by ACE spacecraft orbiting the Earth-Sun Lagrangian point, we selected 48 forward interplanetary shocks(IPSs) occurred in 2000, maximum solar activity period. Examining the profiles of solar wind parameters, the IPSs are classified by their shock drivers.

Signatures of interplanetary transients behind shocks and their associated near-surface solar activity [PDF]
Annales Geophysicae, 1998 Interplanetary transients with particular signatures different from the normal solar wind have been observed behind interplanetary shocks and also without shocks.

Space Weather, 2020 In this study we investigate the ability of several different machine learning models to provide probabilistic predictions as to whether interplanetary shocks observed upstream of the Earth at L1 will lead to immediate (Sudden Commencements, SCs) or ...

Acceleration of Solar Wind Particles by Traveling Interplanetary Shocks [PDF]
Astrophysical Journal, 2019 The acceleration of thermal solar wind (SW) protons at spherical interplanetary shocks driven by coronal mass ejections is investigated. The SW velocity distribution is represented using κ-functions, which are transformed in response to simulated shock ...
