Measuring the Coronal Magnetic Field with 2D Coronal Seismology: A Forward-modeling Validation
The Astrophysical Journal Supplement SeriesIn recent years, a two-dimensional (2D) coronal seismology technique applied to spectral-imaging data from the Coronal Multi-channel Polarimeter (CoMP) and Upgraded Coronal Multi-channel Polarimeter (UCoMP) has enabled routine measurement of the global ...

Kinetic Physics of the Solar Corona and Solar Wind
Living Reviews in Solar Physics, 2006 Kinetic plasma physics of the solar corona and solar wind are reviewed with emphasis on the theoretical understanding of the in situ measurements of solar wind particles and waves, as well as on the remote-sensing observations of the solar corona made by

MHD mode conversion of fast and slow magnetoacoustic waves in the solar corona
, 2010 There are three main wave types present in the Sun’s atmosphere: Alfvén waves and fast and slow magnetoacoustic waves. Alfvén waves are purely magnetic and would not exist if it was not for the Sun’s magnetic field.

Propagating Kink Waves in Chromospheric Jetlike Structures and Coronal Plumelets
The Astrophysical JournalCoronal plumes and chromospheric jetlike structures are believed to be highly dynamic. We report the first direct observations of a propagating kink wave in a chromospheric jetlike structure and its associated plumelet structure in the upper corona of ...

, 2011 Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...

Relativistic-electron dropouts and recovery: A superposed epoch study of the magnetosphere and the solar wind [PDF]
, 2009 During 124 high-speed-stream-driven storms from two solar cycles, a multispacecraft average of the 1.1–1.5 MeV electron flux measured at geosynchronous orbit is examined to study global dropouts of the flux. Solar wind and magnetospheric measurements are

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]
, 2009 Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

The influence of solar wind variability on magnetospheric ULF wave power
, 2015 Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent drift ...
