Abstract Solar Energetic Particle (SEP) events are interesting from a scientific perspective as
they are the product of a broad set of physical processes from the corona out through the …

This review article summarizes the advancement in the studies of Earth-affecting solar
transients in the last decade that encompasses most of solar cycle 24. It is a part of the effort …

Geomagnetic storms are an important aspect of space weather and can result in significant
impacts on space-and ground-based assets. The majority of strong storms are associated …

Coronal mass ejections (CMEs) were discovered in the early 1970s when space-borne
coronagraphs revealed that eruptions of plasma are ejected from the Sun. Today, it is known …

As observed in Thomson-scattered white light, coronal mass ejections (CMEs) are manifest
as large-scale expulsions of plasma magnetically driven from the corona in the most …

We present results from a set of numerical simulations aimed at exploring the mechanism of
coronal mass ejection (CME) suppression in active stars by an overlying large-scale …

Magnetohydrodynamics (MHD)-based global space weather models have mostly been
developed and maintained at academic institutions. While the “free spirit” approach of …

Magnetic fields play a fundamental role in the structure and dynamics of the solar corona. As
they are driven by their footpoint motions on the solar surface, which transport energy from …

Context. Coronal mass ejections (CMEs) are the primary source of strong space weather
disturbances at Earth. Their geo-effectiveness is largely determined by their dynamic …

There have recently been detections of radio emission from low-mass stars, some of which
are indicative of star–planet interactions. Motivated by these exciting new results, in this …
