A SOLAR CORONAL JET EVENT TRIGGERS A CORONAL MASS EJECTION [PDF]
The Astrophysical Journal, 2015 We present the multi-point and multi-wavelength observation and analysis on a solar coronal jet and coronal mass ejection (CME) event in this paper. Employing the GCS model, we obtained the real (three-dimensional) heliocentric distance and direction of the CME and found it propagate in a high speed over 1000 km/s .

THE HELIOCENTRIC DISTANCE WHERE THE DEFLECTIONS AND ROTATIONS OF SOLAR CORONAL MASS EJECTIONS OCCUR [PDF]
, 2015 Understanding the trajectory of a coronal mass ejection (CME), including any deflection from a radial path, and the orientation of its magnetic field is essential for space weather predictions. Kay et al.

Unraveling the Thermodynamic Enigma between Fast and Slow Coronal Mass Ejections
The Astrophysical Journal, 2023 Coronal mass ejections (CMEs) are the most energetic expulsions of magnetized plasma from the Sun that play a crucial role in space weather dynamics.

On the Nature of the Bright Core of Solar Coronal Mass Ejections
Astrophysical Journal, 2019 Coronal mass ejections (CMEs) often exhibit the classic three-part structure in a coronagraph, i.e., the bright front, dark cavity, and bright core, which are traditionally considered as the manifestations of coronal plasma pileup, magnetic flux rope ...

Global Energetics of Solar Flares. V. Energy Closure in Flares and Coronal Mass Ejections [PDF]
, 2017 In this study we synthesize the results of four previous studies on the global energetics of solar flares and associated coronal mass ejections (CMEs), which include magnetic, thermal, nonthermal, and CME energies in 399 solar M- and X-class flare events
