Nanodust dynamics during a coronal mass ejection [PDF]

open access: yesAnnales 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

open access: yesFrontiers 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]

open access: yesIranian 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

Hot prominence detected in the core of a coronal mass ejection [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. We study an erupting prominence embedded in the core of a coronal mass ejection that occurred on August 2, 2000, and focus on deriving the plasma filling factor of the prominence. Aims. We explore two methods for measuring this factor along the

Investigating Remote-Sensing Techniques to Reveal Stealth Coronal Mass Ejections

open access: yesFrontiers 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 ...

The Drag-based Ensemble Model (DBEM) for Coronal Mass Ejection Propagation [PDF]

open access: yes, 2018
The drag-based model for heliospheric propagation of coronal mass ejections (CMEs) is a widely used analytical model that can predict CME arrival time and speed at a given heliospheric location.

Flux Accretion and Coronal Mass Ejection Dynamics [PDF]

open access: yesSolar Physics, 2017
Coronal mass ejections (CMEs) are the primary drivers of severe space weather disturbances in the heliosphere. Models of CME dynamics have been proposed that do not fully include the effects of magnetic reconnection on the forces driving the ejection ...

Coronal Mass Ejections [PDF]

open access: yesAmerican 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,

On the Construction of Phenomenological Coronal Mass Ejection Models

open access: yesSpace 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 ...

The Eruption of a Small-scale Emerging Flux Rope as the Driver of an M-class Flare and of a Coronal Mass Ejection [PDF]

open access: yes, 2017
Solar flares and coronal mass ejections are the most powerful explosions in the Sun. They are major sources of potentially destructive space weather conditions. However, the possible causes of their initiation remain controversial.
