Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. II. Understanding Prominence Eruption through Data-driven Modeling and Observed Magnetic Environment

The Astrophysical Journal
EK Draconis, a nearby young solar-type star (G1.5V, 50–120 Myr), is known as one of the best proxies for inferring the environmental conditions of the young Sun.

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths

The Astronomical Journal
Space weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...

Coronal Mass Ejections: A Study of Structure

, 2017
In this thesis I test a hypothesis that claims coronal mass ejections maintain a structure as they expand into space by means of computer simulation. The first five chapters review the history of coronal mass ejections, what scientists have ascertained ...

Minifilament Eruptions as the Last Straw to Break the Equilibrium of a Giant Solar Filament

The Astrophysical Journal
Filament eruptions are magnetically driven violent explosions commonly observed on the Sun and late-type stars, sometimes leading to monster coronal mass ejections that directly affect the nearby planets’ environments.
