Coronal mass ejection: key issues
Coronal Mass Ejections (CMEs) have been addressed by a particularly active research community in recent years. With the advent of the International Heliophysical Year and the new STEREO and Hinode missions, in addition to the on-going SOHO mission, CME research has taken centre stage in a renewed international effort. This review aims to touch on some key observational areas, and their interpre...
متن کاملThe Coronal Mass Ejection Waiting-time Distribution
The distribution of times ∆t between coronal mass ejections (CMEs) in the Large Angle and Spectrometric Coronagraph (LASCO) CME catalog for the years 1996-2001 is examined. The distribution exhibits a power-law tail ∝ (∆t) with an index γ ≈ −2.36± 0.11 for large waiting times (∆t > 10 hours). The powerlaw index of the waiting-time distribution varies with the solar cycle: for the years 1996-199...
متن کاملFeatures and Properties of Coronal Mass Ejection/flare Current Sheets
Solar eruptions occur when magnetic energy is suddenly converted into heat and kinetic energy by magnetic reconnection in a current sheet (CS). It is often assumed that CSs are too thin to be observable because the electric resistivity in CSs is taken to be very small. In this work, we show the implications for the CS thickness he d estimated from observations of three eruptions by the UVCS and...
متن کاملThe Evolution of a Rapidly Expanding Active Region Loop into a Trans Equatorial Coronal Mass Ejection
On February a coronal mass ejection erupted o the NE limb of the Sun from a coronal loop sys tem which had earlier been visible in soft X rays and Fe XIV The ejection coincided with the onset of a small soft X ray event and it left the corona at a po sition angle of around degrees at around km s This ejection then merged with a much larger event which spanned the equator and became indis tingui...
متن کاملThe Magnetic Topology of Coronal Mass Ejection Sources
In an attempt to test current initiation models of coronal mass ejections (CMEs), with an emphasis on the magnetic breakout model, we inspect the magnetic topology of the sources of 26 CME events in the context of their chromospheric and coronal response in an interval of approximately nine hours around the eruption onset. First, we perform current-free (potential) extrapolations of photospheri...
