Review of Fast Solar Jets and Coronal Mass Ejections [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 The Sun is a magnetically active star. It has a powerful magnetic field that shifts slightly from year to year until it reverses about every eleven years. The sun's magnetic field has many effects, the collection of which is called solar activity such as,

Journal of Space Weather and Space Climate, 2017 The propagation of a coronal mass ejection (CME) to the Earth takes between about 15 h and several days. We explore whether observations of non-thermal microwave bursts, produced by near-relativistic electons via the gyrosynchrotron process, can be used ...

Deflection of Coronal Mass Ejections in Unipolar Ambient Magnetic Fields
The Astrophysical Journal, 2023 The trajectories of coronal mass ejections (CMEs) are often seen to deviate substantially from a purely radial propagation direction. Such deviations occur predominantly in the corona and have been attributed to “channeling” or deflection of the eruptive

The Astrophysical Journal, 2023 A fundamental property of coronal mass ejections (CMEs) is their radial expansion, which determines the increase in the CME radial size and the decrease in the CME magnetic field strength as the CME propagates.

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).

The relationship of coronal mass ejections to streamers [PDF]
Journal of Geophysical Research: Space Physics, 1999 We have examined images from the Large‐Angle and Spectrometric Coronagraph (LASCO) to study the relationship of coronal mass ejections (CMEs) to coronal streamers. We wish to test the suggestion [Low, 1996] that CMEs arise from flux ropes embedded in a streamer erupting and disrupting the streamer. The data span a period of 2 years near Sunspot minimum

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.

Editorial to the Special Issue “Propagation of Coronal Mass Ejections”
Universe, 2023 Coronal mass ejections (CMEs) and their associated shocks are one of the main drivers of heliosphere variability, causing both interplanetary and planetary perturbations [...]

Coronal dimmings associated with coronal mass ejections on the solar limb [PDF]
The Astrophysical Journal, 2020 <p>We studied&#160;43 coronal dimming events associated with Earth-directed&#160;coronal mass ejections (CMEs)&#160;that were&#160;observed in quasi-quadrature by&#160;the SDO and STEREO satellites.&#160;We derived the properties of the dimmings as observed above&#160;the limb by ...
