Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic
particles, and radio bursts. Since the vast majority of these are associated with the eruption …

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 …

Abstract We present the “Drag-Based Model”(DBM) of heliospheric propagation of
interplanetary coronal mass ejections (ICMEs). The DBM is based on the hypothesis that the …

During the thirteenth encounter of the Parker Solar Probe (PSP) mission, the spacecraft
traveled through a topologically complex interplanetary coronal mass ejection (ICME) …

We intend to provide a comprehensive answer to the question on whether all Coronal Mass
Ejections (CMEs) have flux rope structure. To achieve this, we present a synthesis of the …

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 …

The LASCO coronagraphs, in continuous operation since 1995, have observed the
evolution of the solar corona and coronal mass ejections (CMEs) over a full solar cycle with …

The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary
space and affect planetary atmospheres. The effects of Space Weather on Earth and the …

Magnetic flux ropes play a central role in the physics of coronal mass ejections (CMEs).
Although a flux-rope topology is inferred for the majority of coronagraphic observations of …
