Comparative 3D Asymmetric Expansion and Angular Widths Evolution of Fast and Slow Coronal Mass Ejections
Anjali Agarwal, Wageesh Mishra, Jie Zhang +2
The radial and lateral dimensions of coronal mass ejections (CMEs) influence their duration and probability of encounter at Earth. These properties are linked to the expansion spee…
Magnetic Decay Index Profile and Coronal Mass Ejection Speed
Bernhard Kliem, Georgios Chintzoglou, Tibor Török +1
We study the relationship between the speed of coronal mass ejections (CMEs) and the height profile of the ambient magnetic field, quantified by its decay index, n(h). Our sample i…
Magnetic Field-Constrained Ensemble Image Segmentation of Coronal Holes in Chromospheric Observations
Jaime A. Landeros, Michael S. Kirk, C. Nick Arge +5
Coronal Holes (CHs) are large-scale, low-density regions in the solar atmosphere which may expel high-speed solar wind streams that incite hazardous, geomagnetic storms. Coronal an…
What Are the Causes of Super Activity of Solar Active Regions?
Suman K. Dhakal, Jie Zhang
Flare productivity varies among solar active regions (ARs). This study analyzed 20 ARs of contrasting sunspot areas and flare productivities to understand the super flare productiv…
Unraveling the Thermodynamic Enigma between Fast and Slow Coronal Mass Ejections
Soumyaranjan Khuntia, Wageesh Mishra, Sudheer K Mishra +3
Coronal Mass Ejections (CMEs) are the most energetic expulsions of magnetized plasma from the Sun that play a crucial role in space weather dynamics. This study investigates the di…
