Comparative Analysis of Properties of Coronal Mass Ejections at High and Low Apparent Latitudes in 1996–2025

The Astrophysical Journal
This study examines the statistical properties of coronal mass ejections (CMEs) over two and a half solar cycles (1996–2025) using coronal observations from the SOHO LASCO CDAW and CACTus catalogs, supplemented by sunspot number records and in situ ...

The Kinematics and Morphology of Solar Coronal Mass Ejections

, 2012
Solar coronal mass ejections (CMEs) are large-scale eruptions of plasma and magnetic field from the Sun into the corona and interplanetary space. They are the most significant drivers of adverse space weather at Earth and other locations in the heliosphere, so it is important to understand the physics governing their eruption and propagation.

Sun-as-a-star Analysis of the Solar Eruption Source Region Using Hα Spectroscopic Observations of CHASE

The Astrophysical Journal
Sun-as-a-star analyses serve as a bridge for comparative studies on solar and stellar activities. To investigate the typical Sun-as-a-star H α temporal spectral characteristics in solar eruption source regions, we analyzed five different types of solar ...

When Magnetic Field Lines Stretch, Snap, and Expand: A New Look at Solar Flares with L-maps

The Astrophysical Journal
Understanding the three-dimensional evolution of coronal magnetic fields during solar flares remains challenging due to the lack of direct coronal field measurements.
