When plasma particle velocity distributions have multiple, distinct parts, treating each as a separate beam may yield more intuitive results.
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.
The lower-energy particles may play a larger role in magnetic reconnection than previously believed, influencing space weather near Earth.
A new analysis of satellite data could upend conventional wisdom about how solar storms produce their dangerous radiation—not from X-shaped mergers of magnetic field lines but from swirling vortices.
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.
A NASA team used the MESSENGER spacecraft to analyze Mercury's magnetosphere during intense solar wind pressure.
