Criteria of interplanetary parameters causing intense magnetic storms (Dst less than -100nT) [PDF]

Ten intense storms occurred during the 500 days of August 16, 1978 to December 28, 1979. From the analysis of ISEE-3 field and plasma data, it is found that the interplanetary cause of these storms are long-duration, large and negative IMF B sub Z events,

Nonthermal Acceleration of Electrons, Positrons, and Protons at a Nonrelativistic Quasi-parallel Collisionless Shock

The Astrophysical Journal
Energetic positrons have been observed in the interstellar medium, and high-energy positrons with relativistic energies up to approximately 1 TeV have been detected in Galactic cosmic rays.

Interplanetary flow systems associated with cosmic ray modulation in 1977 - 1980 [PDF]

The hydromagnetic flow configurations associated with cosmic ray modulation in 1977 to 1980 were determined using solar wind plasma and magnetic field data from Voyagers 1 and 2 and Helios 1. The modulation was related to two types of large scale systems

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 ...

Intense magnetic fields at 1 AU: Solar cycle 20 [PDF]

Of the intense magnetic fields (greater than 13 gamma) observed at 1 AU during solar cycle 20 (1973-1975), 92% were associated with shocks, stream interfaces, or cold magnetic enhancements (CMEs).

Evidence linking coronal mass ejections with interplanetary magnetic clouds [PDF]

Using proxy data for the occurrence of those mass ejections from the solar corona which are directed earthward, we investigate the association between the post-1970 interplanetary magnetic clouds of Klein and Burlaga and coronal mass ejections.
