The source and engine of coronal mass ejections [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019
Coronal mass ejections (CMEs) are large-scale expulsions of coronal plasma and magnetic field propagating through the heliosphere. Because CMEs are observed by white-light coronagraphs which, by design, occult the solar disc, supporting disc observations (e.g. in EUV, soft X-rays, Halpha and radio) must be employed for the study of their source regions

Coronal mass ejections are not coherent magnetohydrodynamic structures [PDF]

open access: yesScientific 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]

open access: yesLiving Reviews in Solar Physics
Coronal 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.

Predicting the geoeffective properties of coronal mass ejections: current status, open issues and path forward [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019
Much progress has been made in the study of coronal mass ejections (CMEs), the main drivers of terrestrial space weather thanks to the deployment of several missions in the last decade. The flow of energy required to power solar eruptions is beginning to

Stellar coronal mass ejections [PDF]

open access: yesSerbian 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 and their sheath regions in interplanetary space [PDF]

open access: yesLiving 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.

Coronal Mass Ejections: Observations [PDF]

open access: yesLiving Reviews in Solar Physics, 2012
Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic particles, and radio bursts. Since the vast majority of these are associated with the eruption, development, and evolution of coronal mass ejections (CMEs), we ...

Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]

open access: yesData in Brief
Solar 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

Understanding the Origins of Problem Geomagnetic Storms Associated with "Stealth" Coronal Mass Ejections. [PDF]

open access: yesSpace Sci Rev, 2021
Geomagnetic storms are an important aspect of space weather and can result in significant impacts on space- and ground-based assets. The majority of strong storms are associated with the passage of interplanetary coronal mass ejections (ICMEs) in the ...

Radio Observations of Coronal Mass Ejections: Space Weather Aspects

open access: yesFrontiers in Astronomy and Space Sciences, 2020
We review the current state-of-affairs in radio observations of Coronal Mass Ejections (CMEs) from a Space Weather perspective. In particular, we examine the role of radio observations in predicting or presaging an eruption, in capturing the formation ...
