Hunting for stellar coronal mass ejections
, 2022 Solar flares are often accompanied by filament/prominence eruptions, sometimes leading to coronal mass ejections (CMEs). By analogy, we expect that stellar flares are also associated with stellar CMEs whose properties are essential to know the impact on exoplanet habitability.

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet
The Astrophysical JournalStellar 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.

How Magnetic Field Strength Affects Stellar Coronal Mass Ejection Dynamics
The Astrophysical JournalObservations show that stellar coronal mass ejection (CME) candidates display relatively lower kinetic energies compared to expectations from solar flare–CME relations extrapolated to the stellar regime. This behavior was predicted by studies of magnetic

The Astrophysical Journal Supplement SeriesCoronal mass ejections (CMEs) are major drivers of stellar space weather and can strongly influence the habitability of exoplanets. However, compared to the frequent occurrence of white-light flares, confirmed stellar CMEs remain extremely rare.

The Astrophysical JournalCoronal mass ejections (CMEs) are large-scale eruptions of magnetized plasma from stellar coronae, and they are always accompanied by flares. In this study, we present high-resolution spectroscopic observations of a long-duration optical flare on the RS ...

The Astrophysical JournalStellar coronal mass ejections (CMEs) have significant impacts on surrounding exoplanets and stellar evolution. For M-type dwarf stars, hosting close-in habitable zones, frequent and intense stellar CMEs may render their potentially habitable planets ...

A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]
, 2009 The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]
, 2008 We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

Coronal dimming as a proxy for stellar coronal mass ejections [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractSolar coronal dimmings have been observed extensively in the past two decades and are believed to have close association with coronal mass ejections (CMEs). Recent study found that coronal dimming is the only signature that could differentiate powerful flares that have CMEs from those that do not.
