Expansion-induced Three-part Morphology of the 2021 December 4 Coronal Mass Ejection
The Astrophysical JournalThe typical structure of a coronal mass ejection (CME) was identified as a three-part morphology, which includes a bright front, a dark cavity, and a bright core, with the cavity and the core generally regarded as flux rope and eruptive prominence ...

SIP-IFVM: An Observation-based Magnetohydrodynamic Model of a Coronal Mass Ejection
The Astrophysical Journal Supplement SeriesCurrently, achieving a balance between computational efficiency, accuracy, and numerical stability in coronal mass ejection (CME) simulations, particularly in the sub-Alfvénic coronal region, remains a significant challenge.

American Journal of Rising Scholar Activities, 2023 The underlying dynamics of solar processes are a topic of considerable interest, because the events on the surface of the Sun directly affect the environment of our planet. Certain ‘storms’ that erupt in the outer layers of the Sun can propel masses of electrically charged plasma into the solar system. If the path of that material crosses Earth’s orbit,

Earth-affecting solar transients: a review of progresses in solar cycle 24
Progress in Earth and Planetary Science, 2021 This review article summarizes the advancement in the studies of Earth-affecting solar transients in the last decade that encompasses most of solar cycle 24. It is a part of the effort of the International Study of Earth-affecting Solar Transients (ISEST)

Redefining the boundaries of interplanetary coronal mass ejections from observations at the ecliptic plane [PDF]
, 2016 On 2015 January 6-7, an interplanetary coronal mass ejection (ICME) was observed at L1. This event, which can be associated with a weak and slow coronal mass ejection, allows us to discuss on the differences between the boundaries of the magnetic cloud ...

Simulation study on the propagation process of coronal mass ejection
地球与行星物理论评, 2022 Coronal mass ejection (CME) is a kind of space weather phenomenon caused by the intense activity of the sun. Important issues of concern to the space weather community include understanding the propagation and evolution of a particular CME in the corona ...

Proton beam velocity distributions in an interplanetary coronal mass ejection [PDF]
Annales Geophysicae, 2009 The plasma and magnetic-field instruments on the Helios 2 spacecraft, which was on 3 April 1979 located at 0.68 AU, detected an interplanetary coronal mass ejection (ICME) that revealed itself by the typical signature of magnetic field rotation.

A slow coronal mass ejection with rising X-ray source [PDF]
, 2005 An eruptive event, which occurred on 16th April 2002, is discussed. Using images from the Transition Region and Coronal Explorer ( TRACE) at 195 angstrom, we observe a lifting flux rope which gives rise to a slow coronal mass ejection ( CME).

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.
