Coronal dimmings and what they tell us about solar and stellar coronal mass ejections [PDF]

open access: yesLiving Reviews in Solar Physics
Coronal 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]

open access: yesSerbian 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 ...

Hunting for Stellar Coronal Mass Ejections [PDF]

open access: yesProceedings of the International Astronomical Union, 2016
Coronal mass ejections (CMEs) are explosive events that occur basically daily on the Sun. It is thought that these events play a crucial role in the angular momentum and mass loss of late-type stars, and also shape the environment in which planets form ...

Stellar winds, dead zones, and coronal mass ejections [PDF]

open access: yesThe Astrophysical Journal, 1999
Axisymmetric stellar wind solutions are presented, obtained by numerically solving the ideal magnetohydrodynamic (MHD) equations. Stationary solutions are critically analysed using the knowledge of the flux functions.

Modeling a Carrington-scale Stellar Superflare and Coronal Mass Ejection from κ 1 Cet. [PDF]

open access: yesAstrophys 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

open access: yesThe Astrophysical Journal
Stellar 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 Flares, Superflares, and Coronal Mass Ejections—Entering the Big Data Era

open access: yesUniverse
Flares, 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 ...

Constraining the Mass Loss and the Kinetic Energy of Stellar Coronal Mass Ejections with Solar Far-ultraviolet Flares

open access: yesThe Astrophysical Journal
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres.

From Starspots to Stellar Coronal Mass Ejections—Revisiting Empirical Stellar Relations [PDF]

open access: yesThe 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

Indications of stellar coronal mass ejections through coronal dimmings [PDF]

open access: yesNature 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.
