Coronal Mass Ejections: A Study of Structure

, 2017
In this thesis I test a hypothesis that claims coronal mass ejections maintain a structure as they expand into space by means of computer simulation. The first five chapters review the history of coronal mass ejections, what scientists have ascertained ...

Coronal Mass Ejections: Their Propagation and Associated Storms in the First Phase of Solar Cycle 25

, 2023
We have investigated of about 50 coronal mass ejections from 2022 to 2024 in first phase of solar cycle 25. We have investigated about the velocities, angular widths and central width of those coronal mass ejections.

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet

The Astrophysical Journal
Stellar flares and coronal mass ejections (CMEs) can strip planetary atmospheres, reducing the potential habitability of terrestrial planets. While flares have been observed for decades, stellar CMEs remain elusive.

Statistical Properties of Small‐Scale Magnetic Flux Ropes in the Near‐Earth Solar Wind

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a statistical analysis of small‐scale magnetic flux ropes (SMFRs) observed in the near‐Earth solar wind using data from the Magnetospheric Multiscale (MMS) and Wind spacecraft, identified through an automated Grad–Shafranov reconstruction technique.

Constraining the Mass Loss and the Kinetic Energy of Stellar Coronal Mass Ejections with Solar Far-ultraviolet Flares

The Astrophysical Journal
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres.

Solar Energetic Particle Forecasting With Multi‐Task Deep Learning: SEPNET

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Solar energetic particle (SEP) events pose severe threats to spacecraft, astronaut safety, and aviation operations. Accurate SEP forecasting remains a critical challenge in space weather research as a result of their complex origins and highly variable propagation.

Intelligent prediction model for geoeffectiveness of coronal mass ejections

Frontiers in Astronomy and Space Sciences
Predicting the geoeffectiveness of coronal mass ejections (CMEs) is a core issue in operational space weather forecasting. In recent years, deep learning methods have been increasingly applied to CME geoeffectiveness prediction. However, existing studies

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.

Investigating Alfvénic wave propagation in coronal open-field regions

, 2015
The physical mechanisms behind accelerating solar and stellar winds are a long-standing astrophysical mystery, although recent breakthroughs have come from models invoking the turbulent dissipation of Alfvén waves.
