Indications of stellar coronal mass ejections through coronal dimmings [PDF]
Nature Astronomy, 2021 Coronal mass ejections (CMEs) are huge expulsions of magnetized matter from the Sun and stars, traversing space with speeds of millions of kilometers per hour. Solar CMEs can cause severe space weather disturbances and consumer power outages on Earth, whereas stellar CMEs may even pose a hazard to the habitability of exoplanets.

Effect of stellar flares and coronal mass ejections on the atmospheric escape from hot Jupiters [PDF]
Proceedings of the International Astronomical Union, 2021 AbstractSpectral observations in the Ly-α line have shown that atmospheric escape is variable and for the exoplanet HD189733b, the atmospheric evaporation goes from undetected to enhanced evaporation in a 1.5 years interval. To understand the temporal variation in the atmospheric escape, we investigate the effect of flares, winds, and CMEs on the ...

Tuning the Exospace Weather Radio for Stellar Coronal Mass Ejections [PDF]
The Astrophysical Journal, 2020 Abstract Coronal mass ejections (CMEs) on stars other than the Sun have proven very difficult to detect. One promising pathway lies in the detection of type II radio bursts. Their appearance and distinctive properties are associated with the development of an outward propagating CME-driven shock.

Solar Coronal Mass Ejections Plasma Diagnostics Expressed as Potential Stellar CME Signatures [PDF]
The Astronomical Journal, 2022 Abstract Solar coronal mass ejections (CMEs) have a strong association with solar flares that is not fully understood. This characteristic of our Sun’s magnetic activity may also occur on other stars, but the lack of successfully detected stellar CMEs makes it difficult to perform statistical studies that might show a similar association

Solar and Stellar Coronal Mass Ejections - a review of the Cool Stars 21 splinter session
, 2023 Coronal mass ejections (CMEs) are the most energetic phenomena related to magnetic activity and, by impacting the interplanetary space, they can be the source of severe planetary disturbances. Solar CMEs and their sources, such as flares and filament/prominence eruptions, have been intensively observed and studied over decades.

Magnetic interaction of stellar coronal mass ejections with close-in exoplanets: implication on planetary mass loss and Ly-$α$ transits [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Coronal mass ejections (CMEs) erupting from the host star are expected to affect the atmospheric erosion processes of planets. For planets with a magnetosphere, the embedded magnetic field in the CMEs is thought to be the most important parameter to affect planetary mass-loss. In this work, we investigate the effect of different

The Search for Stellar Coronal Mass Ejections [PDF]
, 2017 Coronal mass ejections (CMEs) may dramatically impact habitability and atmospheric composition of planets around magnetically active stars, including young solar analogs and many M dwarfs. Theoretical predictions of such effects are limited by the lack of observations of stellar CMEs. This thesis addresses this gap through a search for the spectral and

Constraining Stellar Coronal Mass Ejections through Multi-wavelength Analysis of the Active M Dwarf EQ Peg [PDF]
The Astrophysical Journal, 2018 Abstract Stellar coronal mass ejections remain experimentally unconstrained, unlike their stellar flare counterparts, which are observed ubiquitously across the electromagnetic spectrum. Low-frequency radio bursts in the form of a type II burst offer the best means of identifying and constraining the rate and properties of stellar CMEs ...
