Initiation of a coronal mass ejection [PDF]

open access: bronzeGeophysical Research Letters, 2000
There are by now only one or two examples to show the initiation of coronal mass ejections (CMEs). In this paper we present a clear instance of a CME initiation. The enhanced disturbance was seen as the slow upward motion in segments of a prominence. Four hours later, the prominence was accelerated to about 60 km s−1.

Effects of Coronal Mass Ejections on Distant Coronal Streamers [PDF]

open access: yesAstronomy Reports, 2014
The effects of a large coronal mass ejection (CME) on a solar coronal streamer located roughly 90 degrees from the main direction of the CME propagation observed on January 2, 2012 by the SOHO/LASCO coronagraph are analyzed.

Why does the apparent mass of a coronal mass ejection increase? [PDF]

open access: yes, 2015
Mass is one of the most fundamental parameters characterizing the dynamics of a coronal mass ejection (CME). It has been found that CME apparent mass measured from the brightness enhancement in coronagraph images shows an increasing trend during its ...

Genesis and Impulsive Evolution of the 2017 September 10 Coronal Mass Ejection [PDF]

open access: yesAstrophysical Journal, 2018
The X8.2 event of 2017 September 10 provides unique observations to study the genesis, magnetic morphology, and impulsive dynamics of a very fast coronal mass ejection (CME). Combining GOES-16/SUVI and SDO/AIA EUV imagery, we identify a hot (T ≈ 10–15 MK)

Stellar coronal mass ejections

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 exoplanetary atmospheres.

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

The probable excitation mechanism of kink oscillations of coronal loops [PDF]

open access: yesIranian Journal of Physics Research, 2022
Oscillations in various structures of the solar atmosphere, such as transverse (kink) oscillations of coronal loops, can be used in seismology. Transvers kink oscillations of coronal loops are often accompanied by solar flares.

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,
