Planar magnetic structures in coronal mass ejection-driven sheath regions [PDF]
Annales Geophysicae, 2016 Planar magnetic structures (PMSs) are periods in the solar wind during which interplanetary magnetic field vectors are nearly parallel to a single plane.

Observations of flux rope formation prior to coronal mass ejections [PDF]
, 2013 Understanding the magnetic configuration of the source regions of coronal mass ejections (CMEs) is vital in order to determine the trigger and driver of these events.

Deciphering the Slow-rise Precursor of a Major Coronal Mass Ejection
The Astrophysical Journal Letters, 2023 Coronal mass ejections are explosive plasma phenomena prevalently occurring on the Sun and probably on other magnetically active stars. However, how their pre-eruptive configuration evolves toward the main explosion remains elusive.

The Inhomogeneity of Composition Along the Magnetic Cloud Axis
Frontiers in Physics, 2021 Coronal mass ejections (CMEs) are one of the most energetic explosions in the solar system. It is generally accepted that CMEs result from eruptions of magnetic flux ropes, which are dubbed as magnetic clouds (MCs) in interplanetary space.

Solar Coronal Mass Ejections [PDF]
Symposium - International Astronomical Union, 1990 In addition to the more or less steady solar wind, the Sun also ejects mass in highly time dependent events taking place in the corona once every few days at solar activity minimum and as often as three times a day at solar activity maximum (Hundhausen 1988, Low 1986).

Effect of an Interplanetary Coronal Mass Ejection on Saturn’s Radio Emission
Frontiers in Astronomy and Space Sciences, 2022 The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are emitted by electrons travelling around auroral magnetic ...

Estimation of a coronal mass ejection magnetic field strength using radio observations of gyrosynchrotron radiation [PDF]
, 2017 Coronal mass ejections (CMEs) are large eruptions of plasma and magnetic field from the low solar corona into interplanetary space. These eruptions are often associated with the acceleration of energetic electrons which produce various sources of high ...

Coronal Mass Ejections and Coronal Structures [PDF]
, 1989 The coronal portion of the solar atmosphere consists of a wide variety of structures which exhibit a similarly wide variety of dynamical processes and kinds of activity. The launch of the SMM presented an opportunity to study the low and intermediate corona from space with multiple instruments for protracted periods of time.
