The birth of a coronal mass ejection. [PDF]
Sci Adv, 2019 The Sun's atmosphere is frequently disrupted by coronal mass ejections (CMEs), coupled with flares and energetic particles. In the standard picture, the coupling is explained by magnetic reconnection at a vertical current sheet connecting the flare loops

Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]
Data in BriefSolar flares and coronal mass ejections are solar transient events that can impact our technological infrastructure in near-Earth and Earth environments. While related, not all flares generate CMEs and there are a limited number of resources that connect

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.

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 ...

Reconnection in a slow Coronal Mass Ejection [PDF]
Annales Geophysicae, 2008 This paper aims at studying reconnection occurring in the aftermath of the 28 May 2004, CME, first imaged by the LASCO (Large Angle and Spectrometric Coronagraph) C2 at 11:06 UT. The CME was observed in White Light and UV radiation: images acquired by

Nanodust dynamics during a coronal mass ejection [PDF]
Annales Geophysicae, 2017 The dynamics of nanometer-sized grains (nanodust) is strongly affected by electromagnetic forces. High-velocity nanodust was proposed as an explanation for the voltage bursts observed by STEREO.

The evolution of our understanding of coronal mass ejections
Frontiers in Astronomy and Space Sciences, 2023 The unexpected observation of a sudden expulsion of mass through the solar corona in 1971 opened up a new field of interest in solar and stellar physics.

Effect of Latitude of Sunspots on Earth-Intersecting Trajectory of Plasma [PDF]
Iranian Journal of Astronomy and Astrophysics, 2020 Solar flares and Coronal Mass Ejections form around the edges of sunspots. If the plasma from such events is incident on the Earth’s magnetosphere, significant disruptions to electrical systems can occur. However, sunspots occur around the surface of the

Investigating Remote-Sensing Techniques to Reveal Stealth Coronal Mass Ejections
Frontiers in Astronomy and Space Sciences, 2021 Eruptions of coronal mass ejections (CMEs) from the Sun are usually associated with a number of signatures that can be identified in solar disc imagery. However, there are cases in which a CME that is well observed in coronagraph data is missing a clear ...

On the Construction of Phenomenological Coronal Mass Ejection Models
Space Weather, 2021 We consider recently developed 3DCORE coronal mass ejection (CME) model. We find that the magnetic field of 3DCORE violates both Maxwellian equations: the one for absence of magnetic monopoles and the other one for Faraday induction (“frozen‐in ...
