The birth of a coronal mass ejection. [PDF]
Sci Adv, 2019 Tiny plasmoids merge on the Sun and snowball into a stellar-sized eruption. The Sun’s atmosphere is frequently disrupted by coronal mass ejections (CMEs), coupled with flares and energetic particles.

Planar magnetic structures in coronal mass ejection-driven sheath regions [PDF]
Annales Geophysicae, 2016 Planar magnetic structures (PMSs) are periods in the solar wind during which interplanetary magnetic field vectors are nearly parallel to a single plane.

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

Source Regions of Coronal Mass Ejections [PDF]
Symposium - International Astronomical Union, 2001 Observations of the solar corona with the LASCO and EIT instruments on SOHO provide an unprecedented opportunity to study coronal mass ejections (CMEs) from their initiation through their evolution out to 30 R⊙. The objective of this study is to gain an understanding of the source regions from which the CMEs emanate.

Initiation of a coronal mass ejection [PDF]
Geophysical 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.

Genesis and Impulsive Evolution of the 2017 September 10 Coronal Mass Ejection [PDF]
Astrophysical 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
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 exoplanetary atmospheres.

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

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.
