Decoding the Pre-Eruptive Magnetic Field Configurations of Coronal Mass Ejections
Space Science Reviews, 2020A clear understanding of the nature of the pre-eruptive magnetic field configurations of Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting solar eruptions. Only two, but seemingly disparate, magnetic configurations are

Physics of Plasmas, 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 ...

In this paper, we compare Forbush decreases associated with solar wind disturbances from two types of solar sources: coronal mass ejections (sporadic Forbush decreases) and coronal holes (recurrent Forbush decreases).

Stellar coronal mass ejections (CMEs) remain observationally elusive, but could have important implications for exoplanet habitability. Low-frequency radio bursts, known as Type IIs in the solar context, offer the best means to identify stellar CMEs ...

Abstract We summarize the observational aspects of the transient solar coronal features known as coronal mass ejections. Recognizing the importance of understanding this form of solar activity, particularly in the light of relations to flare and prominence activity, and geomagnetic effects, we consider the spectrum of models which ...

Detection and Tracking of Coronal Mass Ejections
2008Coronal Mass Ejection (CME) events refer to the appearance of a new, discrete, white-light feature (with outward velocity) in a coronagraph. The huge amount of data provided by the pertinent instruments onboard the Solar and Heliospheric Observatory (SOHO) and, most recently, the Solar Terrestrial Relations Observatory (STEREO) makes the human-based ...

Forces governing coronal mass ejections
Advances in Space Research, 2006Kinematics of CMEs is analyzed to get an insight into the properties of forces partaking in the eruption. It is demonstrated that the Lorentz force plays a dominant role within a distance of a few solar radii. In the distance range 1– 30 solar radii, the inferred values of the Lorentz-force acceleration aL on average decrease with the ...

Turbulence in coronal mass ejections
Journal of Geophysical Research: Space Physics, 1997The magnetic fields measured by the ISEE 3 spacecraft are used to study MHD turbulence within coronal mass ejections (CMEs). The spectral indices of the turbulence inside CMEs are compared with spectral indices found in solar wind undisturbed by CMEs. Irrespective of the CME velocities, the spectra within CMEs are found to differ from those determined ...

Fitting and Reconstruction of Thirteen Simple Coronal Mass Ejections
, 2018Coronal mass ejections (CMEs) are the main drivers of geomagnetic disturbances, but the effects of their interaction with Earth’s magnetic field depend on their magnetic configuration and orientation.
