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

Estimation of a coronal mass ejection magnetic field strength using radio observations of gyrosynchrotron radiation [PDF]
, 2017 Coronal mass ejections (CMEs) are large eruptions of plasma and magnetic field from the low solar corona into interplanetary space. These eruptions are often associated with the acceleration of energetic electrons which produce various sources of high ...

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.

Interplanetary Propagation Behavior of the Fast Coronal Mass Ejection on 23 July 2012 [PDF]
, 2014 The fast coronal mass ejection (CME) on 23 July 2012 caused attention because of its extremely short transit time from the Sun to 1 AU, which was shorter than 21 h.

Solar Coronal Mass Ejection and Post–Coronal Mass Ejection Blob Formation in Two-fluid Simulations
The Astrophysical JournalA 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.

The Astrophysical Journal Supplement SeriesCoronal 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 ...

Coronal Mass Ejection–Associated Coronal Dimmings
The Astrophysical Journal, 2008 We report on a statistical analysis of 96 CME-associated EUV coronal dimmings between 1998 and 2000. We investigate the size and location of the events and characterize how these events evolve with time. The durations typically range from 3 to 12 hr. The dimmings appear most frequently within the belt of active regions (20°-50° latitude).

Deflected propagation of a coronal mass ejection from the corona to interplanetary space [PDF]
, 2014 Among various factors affecting the space weather effects of a coronal mass ejection (CME), its propagation trajectory in the interplanetary space is an important one determining whether and when the CME will hit the Earth.
