Coronal Mass Ejections and Coronal Structures [PDF]

, 1989
The coronal portion of the solar atmosphere consists of a wide variety of structures which exhibit a similarly wide variety of dynamical processes and kinds of activity. The launch of the SMM presented an opportunity to study the low and intermediate corona from space with multiple instruments for protracted periods of time.

Periodicities in solar coronal mass ejections [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (February 5, 1999 to February 10, 2003) of the Large Angle Spectrometric Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO).

Solar jet-coronal hole collision and a related coronal mass ejection

, 2016
Jets are defined as impulsive, well-collimated upflows, occurring in different layers of the solar atmosphere with different scales. Their relationship with coronal mass ejections (CMEs), another type of solar impulsive events, remains elusive. Using the

The Coronal Analysis of SHocks and Waves (CASHeW) Framework [PDF]

, 2017
Coronal Bright Fronts (CBF) are large-scale wavelike disturbances in the solar corona, related to solar eruptions. They are observed in extreme ultraviolet (EUV) light as transient bright fronts of finite width, propagating away from the eruption source.

Flux Rope Formation Preceding Coronal Mass Ejection Onset

, 2009
We analyse the evolution of a sigmoidal (S shaped) active region toward eruption, which includes a coronal mass ejection (CME) but leaves part of the filament in place.

Eruptive Event Generator Based on the Gibson-Low Magnetic Configuration [PDF]

, 2017
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one of the primary means of studying ...

Solar Coronal Mass Ejection and Post–Coronal Mass Ejection Blob Formation in Two-fluid Simulations

The Astrophysical Journal
A coronal mass ejection (CME) and post-CME blob phenomena in the solar atmosphere, associated with shear flow and convergent flow perturbations in the photosphere, are investigated using a resistive two-fluid (electron–ion) code.

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain

Advanced Science, EarlyView.
OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.

CAMEL. II. A 3D Coronal Mass Ejection Catalog Based on Coronal Mass Ejection Automatic Detection with Deep Learning

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are major drivers of geomagnetic storms, which may cause severe space weather effects. Automating the detection, tracking, and three-dimensional (3D) reconstruction of CMEs is important for operational predictions of CME ...
