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 ...

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 ...

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.

Analysis of coronal mass ejections and solar flares
International Journal of Innovative Research and Growth, 2022 The Sun is the most conspicuous element in our nearby planet group and contains around 98% of the all out planetary group mass. In this work we have selected those CME events which are having velocity >=500 Km/s with an apparent width of 3600 during the period from 2008-2019 (SC24).Within this time frame we have observed 201 CME events and ...

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
