Coronal dimmings and what they tell us about solar and stellar coronal mass ejections [PDF]
Living Reviews in Solar PhysicsCoronal dimmings associated with coronal mass ejections (CMEs) from the Sun have gained much attention since the late 1990s when they were first observed in high-cadence imagery of the SOHO/EIT and Yohkoh/SXT instruments.

Stellar coronal mass ejections [PDF]
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect ...

Stellar Flares, Superflares, and Coronal Mass Ejections—Entering the Big Data Era [PDF]
UniverseFlares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden changes in the magnetic field of stars with high energy release through magnetic reconnection, which can be observed across a wide range of the electromagnetic ...

From Starspots to Stellar Coronal Mass Ejections—Revisiting Empirical Stellar Relations [PDF]
Astrophysical Journal, 2021 Abstract Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type stars by searching for atmospheric biosignatures. Recent observations suggest that the ionizing radiation and particle environment from active cool planet

Modeling a Carrington-scale Stellar Superflare and Coronal Mass Ejection from κ 1 Cet. [PDF]
Astrophys J, 2019 Abstract Observations from the Kepler mission have revealed frequent superflares on young and active solar-like stars. Superflares result from the large-scale restructuring of stellar magnetic fields, and are associated with the eruption of coronal material (a coronal mass ejection, or CME) and energy release that can be orders of ...

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.

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 ...

Tuning the Exospace Weather Radio for Stellar Coronal Mass Ejections [PDF]
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.
