Detection of Stellar Mass Ejections through Extreme Ultraviolet Spectral Lines

The Astrophysical Journal
Coronal mass ejections (CMEs), since their first observation in 1971, have been widely acknowledged as the most significant eruptive phenomena and the primary cause of catastrophic space weather events within our solar system.

Global Disaster Forecasting with Space Weather and Geophysical Intelligence [PDF]

Journal of Systemics, Cybernetics and Informatics, 2020
There are many opportunities to integrate Space Weather data into global weather and Natural Disaster Forecasting models. The Earth as a Stellar Transformer Hypothesis builds on the Global Electrical Circuit model.

A New Phase for Space Weather

Space Weather, Volume 24, Issue 4, April 2026.
Abstract As we move into the declining phase of solar cycle 25, the sunspot number is going down but space weather impacts are not disappearing. Solar energetic particle events, large x‐ray flares, and geomagnetic storms are still happening and the declining phase will bring a different balance of hazards.

A Census of Near-UV M-dwarf Flares Using Archival GALEX Data and the gPHOTON2 Pipeline

The Astrophysical Journal, 2023
M-dwarfs are common stellar hosts of habitable-zone exoplanets. Near-UV (NUV) radiation can severely impact the atmospheric and surface conditions of such planets, making the characterization of NUV flaring activity a key aspect in determining ...

Impact of Solar Irradiance on Storm‐Time Thermospheric Mass Density Response

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract As a key parameter in the externally forced ionosphere–thermosphere (IT) system, mass density response to storms is affected by the prevailing solar irradiance. To better understand this relationship, we examine mass density responses to the same storm but with different background solar irradiance levels.

Is It Possible to Detect Coronal Mass Ejections on Solar-type Stars through Extreme-ultraviolet Spectral Observations?

The Astrophysical Journal
Stellar coronal mass ejections (CMEs) from host stars are an important factor that affects the habitability of exoplanets. Although their solar counterparts have been well observed for decades, it is still very difficult to find solid evidence of stellar

Propagation of an Earth-directed coronal mass ejection in three dimensions

, 2010
Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood.

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...
