Coalescence of Magnetic Flux Ropes Within Interplanetary Coronal Mass Ejections: Multi-cases Studies

Frontiers in Physics, 2019
Coronal mass ejections (CMEs) are intense solar explosive eruptions and have significant impact on geomagnetic activities. It is important to understand how CMEs evolve as they propagate in the solar-terrestrial space.

Rotation of a Stealth CME on 2012 October 5 Observed in the Inner Heliosphere

The Astrophysical Journal, 2023
Coronal mass ejections (CMEs) are subject to changes in their direction of propagation, tilt, and other properties. This is because CMEs interact with the ambient solar wind and other large-scale magnetic field structures.

Solar Wind and Heavy Ion Properties of Interplanetary Coronal Mass Ejections

Solar Physics, 2018
Magnetic field and plasma properties of the solar wind measured in near-Earth space are a convolution of coronal source conditions and in-transit processes which take place between the corona and near-Earth space.

Is There a Dynamic Difference between Stealthy and Standard Coronal Mass Ejections?

The Astrophysical Journal, 2022
Stealthy coronal mass ejections (CMEs), lacking low coronal signatures, may result in significant geomagnetic storms. However, the mechanism of stealthy CMEs is still highly debated.

Proton Temperature Anisotropy within the Interplanetary Coronal Mass Ejections Sheath at 1 au

The Astrophysical Journal Letters, 2023
The sheath plasma of interplanetary coronal mass ejections (ICMEs) is highly compressed, heated, turbulent, and magnetically intense relative to the ambient solar wind.

Energetics of a Solar Flare and a Coronal Mass Ejection Generated by a Hot Channel Eruption

The Astrophysical Journal, 2023
Hot channels (HCs) are prevalent in the solar corona and play a critical role in driving flares and coronal mass ejections (CMEs). In this paper, we estimate the energy content of an X1.4 eruptive flare with a fast CME generated by an HC eruption on 2011

Coronal Mass Ejections and Solar Polarity Reversal

The Astrophysical Journal, 2003
We report on a close relationship between the solar polarity reversal and the cessation of high-latitude coronal mass ejections (CMEs). This result holds good for individual poles of the Sun for cycles 21 and 23, for which CME data are available. The high-latitude CMEs provide a natural explanation for the disappearance of the polar crown filaments ...

Physics of erupting solar flux ropes: Coronal mass ejections (CMEs)—Recent advances in theory and observation

, 2017
Solar eruptions, observed as flares and coronal mass ejections (CMEs), are the most energetic visible plasma phenomena in the solar system. CMEs are the central component of solar eruptions and are detected as coherent magnetized plasma structures ...
