Stellar coronal mass ejections – II. Constraints from spectroscopic observations [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Detections of stellar coronal mass ejections (CMEs) are still rare. Observations of strong Balmer line asymmetries during flare events have been interpreted as being caused by CMEs. Here, we aim to estimate the maximum possible Balmer line fluxes expected from CMEs to infer their detectability in spectroscopic observations ...

The Astrophysical Journal, 2023 Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blueshifted excess component of Balmer lines is a ...

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.

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.

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.

The Astrophysical Journal, 2023 Coronal mass ejections (CMEs) are violent ejections of magnetized plasma from the Sun that can trigger geomagnetic storms, endanger satellite operations, and destroy electrical infrastructures on the Earth.

Detection of Coronal Mass Ejections in V471 Tauri with the Hubble Space Telescope [PDF]
, 2001 V471 Tauri, an eclipsing system consisting of a hot DA white dwarf (WD) and a dK2 companion in a 12.5-hour orbit, is the prototype of the pre-cataclysmic binaries.
