Stellar coronal mass ejections [PDF]
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect ...

Coronal mass ejections are not coherent magnetohydrodynamic structures [PDF]
Scientific Reports, 2017 Coronal mass ejections (CMEs) are episodic eruptions of solar plasma and magnetic flux that travel out through the solar system, driving extreme space weather. Interpretation of CME observations and their interaction with the solar wind typically assumes

Coronal dimmings and what they tell us about solar and stellar coronal mass ejections [PDF]
Living Reviews in Solar PhysicsCoronal dimmings associated with coronal mass ejections (CMEs) from the Sun have gained much attention since the late 1990s when they were first observed in high-cadence imagery of the SOHO/EIT and Yohkoh/SXT instruments.

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

Causal relationships between eruptive prominences and coronal mass ejections [PDF]
Annales Geophysicae, 2008 A close association between eruptive prominences and CMEs, both slow and fast CMEs, was reported in many studies. Sometimes it was possible to follow the material motion starting from the prominence (filament) activation to the CME in the high corona.

Coronal mass ejections and their sheath regions in interplanetary space [PDF]
Living Reviews in Solar Physics, 2017 Interplanetary coronal mass ejections (ICMEs) are large-scale heliospheric transients that originate from the Sun. When an ICME is sufficiently faster than the preceding solar wind, a shock wave develops ahead of the ICME.

Space Weather, 2021 Predicting the Bz magnetic field embedded within interplanetary coronal mass ejections (ICMEs), also known as the Bz problem, is a key challenge in space weather forecasting. We study the hypothesis that upstream in situ measurements of the sheath region

Lateral Confinement and the Remarkably Self-similar Nature of Coronal Pseudostreamer Mass Ejections
The Astrophysical Journal, 2023 Coronal mass ejections (CMEs) that originate from pseudostreamers, which separate coronal holes of the same magnetic polarity, are characterized by a narrow (∼5°–30°), fan-shaped appearance in white-light coronagraph images.

Review of Fast Solar Jets and Coronal Mass Ejections [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 The Sun is a magnetically active star. It has a powerful magnetic field that shifts slightly from year to year until it reverses about every eleven years. The sun's magnetic field has many effects, the collection of which is called solar activity such as,

What Do Halo CMEs Tell Us about Solar Cycle 25?
The Astrophysical Journal Letters, 2023 It is known that the weak state of the heliosphere due to diminished solar activity in cycle 24 backreacted on coronal mass ejections (CMEs) to make them appear wider for a given speed. One of the consequences of the weak state of the heliosphere is that
