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.

First imaging of corotating interaction regions using the STEREO spacecraft [PDF]
, 2008 Plasma parcels are observed propagating from the Sun out to the large coronal heights monitored by the Heliospheric Imagers (HI) instruments onboard the NASA STEREO spacecraft during September 2007. The source region of these out-flowing parcels is found

Hunting for Stellar Coronal Mass Ejections [PDF]
Proceedings of the International Astronomical Union, 2016 AbstractCoronal 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 and live.

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 ...

Stellar Winds, Dead Zones, and Coronal Mass Ejections [PDF]
The Astrophysical Journal, 2000 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. These flux functions enter in the general variational principle governing all axisymmetric stationary ideal MHD equilibria.

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 ...

Where are the stellar coronal mass ejections?
, 2022 Stellar flares and coronal mass ejections (CMEs) can have serious effects on their surroundings: they can erode or completely destroy atmospheres of orbiting planets over time and also have high importance in stellar evolution. Most of the stellar CME detections in the literature are single events found serendipitously sparse for statistical ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.
