Journal ArticleDOI
Neutral line model of substorms: Past results and present view
Daniel N. Baker,Tuija Pulkkinen,Vassilis Angelopoulos,Wolfgang Baumjohann,Robert L. McPherron +4 more
TL;DR: In this article, the authors reviewed the NENL model of magnetospheric substorms, including the role of coupling with the solar wind and interplanetary magnetic field, the growth phase sequence, the expansion phase (and onset), and the recovery phase.
Journal ArticleDOI
Rapid local acceleration of relativistic radiation-belt electrons by magnetospheric chorus
Richard M. Thorne,Wen Li,Binbin Ni,Qianli Ma,Jacob Bortnik,Lunjin Chen,Daniel N. Baker,Harlan E. Spence,Geoffrey D. Reeves,Michael G. Henderson,Craig Kletzing,William S. Kurth,George Hospodarsky,J. B. Blake,Joseph F. Fennell,Seth G. Claudepierre,Shrikanth Kanekal +16 more
TL;DR: High-resolution electron observations obtained during the 9 October storm are reported and chorus scattering explains the temporal evolution of both the energy and angular distribution of the observed relativistic electron flux increase, and detailed modelling demonstrates the remarkable efficiency of wave acceleration in the Earth's outer radiation belt.
Journal ArticleDOI
The Mars Atmosphere and Volatile Evolution (MAVEN) Mission

TL;DR: The MAVEN spacecraft has eight science instruments (with nine sensors) that measure the energy and particle input from the Sun into the Mars upper atmosphere, the response of the upper atmosphere to that input, and the resulting escape of gas to space as mentioned in this paper.
Journal ArticleDOI

TL;DR: For example, NASA's magnetospheric multiscale (MMS) mission has found direct evidence for electron demagnetization and acceleration at sites along the sunward boundary of Earth's magnetosphere where the interplanetary magnetic field reconnects with the terrestrial magnetic field as discussed by the authors.
Journal ArticleDOI
Wave acceleration of electrons in the Van Allen radiation belts
Richard B. Horne,Richard M. Thorne,Yuri Shprits,Nigel P. Meredith,Sarah A. Glauert,Andrew Smith,Shrikanth Kanekal,Daniel N. Baker,Mark J. Engebretson,J. L. Posch,Maria Spasojevic,Umran S. Inan,Jolene S. Pickett,Pierrette Décréau +13 more
TL;DR: It is shown, on the basis of the analysis of a rare event where the outer radiation belt was depleted and then re-formed closer to the Earth, that the long established theory of acceleration by radial diffusion is inadequate; the electrons are accelerated more effectively by electromagnetic waves at frequencies of a few kilohertz.
