A Coronal Mass Ejection Source Region Catalog and Their Associated Properties

The Astrophysical Journal Supplement Series, 2023
The primary objective of this study is to connect coronal mass ejections (CMEs) to their source regions, primarily to create a CME source region catalog, and secondarily to probe the influence that the source regions have on the different statistical ...

Key Signatures of Prominence Materials and Category of Cold Materials Identified by Random Forest Classifier

The Astrophysical Journal Supplement Series, 2023
The origin of cold materials identified by different criteria is unclear. They are highly suspected to be erupted prominences. However, some cold materials defined by charge depletion exist in both quiet solar wind and interplanetary coronal mass ...

STOCHASTICITY AND PERSISTENCE OF SOLAR CORONAL MASS EJECTIONS

The Astrophysical Journal, 2013
The study of the statistical properties of coronal mass ejections (CMEs) reveals that their properties depend on the period of solar activity. In particular, when investigating the origin of the waiting time distribution between CMEs, a significant departure from a Poisson process during periods of high solar activity has been found, thus suggesting ...

Spatial Relationship between Solar Flares and Coronal Mass Ejections [PDF]

The Astrophysical Journal, 2008
We report on the spatial relationship between solar flares and coronal mass ejections (CMEs) observed during 1996-2005 inclusive. We identified 496 flare-CME pairs considering limb flares (distance from central meridian > 45 deg) with soft X-ray flare size > C3 level. The CMEs were detected by the Large Angle and Spectrometric Coronagraph (LASCO)

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.

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.

Investigating the Magnetic Structure of Interplanetary Coronal Mass Ejections Using Simultaneous Multispacecraft In Situ Measurements

The Astrophysical Journal, 2023
In situ measurements from spacecraft typically provide a time series at a single location through coronal mass ejections (CMEs), and they have been one of the main methods to investigate CMEs.

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.
