• New findings on the electron ring current enhancement

  In the resent study, Bernhard Haas and co-authors found that the enhancement of the electron ring current during the geomagnetic storms is challenging to reproduce in the modeling, and it is attributed to a new missing scattering processes. Charged particles from space are captured by the Earth’s magnetic field. They then flow in a circular … Continue reading →

• Electrons approach the speed of light when plasma density is low

  In a recent study, Allison et al. found that depletions in plasma allowed electrons to accelerate to ultra-relativistic energies. The study used data from the Van Allen Probes as well as machine learning techniques to make these findings, which were published in Space Advances. “This study shows that electrons in the Earth’s radiation belt can … Continue reading →

• Strong whistler mode waves observed in the vicinity of Jupiter’s moons

  In the vicinity of Europa and Ganymede, that respectively have induced and internal magnetic fields, chorus wave power is significantly increased. The observed enhancements are persistent and exceed median values of wave activity by up to 6 orders of magnitude for Ganymede. Produced waves may have a pronounced effect on the acceleration and loss of … Continue reading →

• Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts

  A geomagnetic storm on January 17, 2013, provided unique observations that finally resolved a long-standing scientific problem.
