دستهبندی تاریکیهای کوچکمقیاس از فورانهای تابشهای فرابنفش دور خورشید با استفاده از نظریه گراف
Coronal dimmings in both micro and macro scales, can be observed by extreme ultraviolet images, recorded from Solar Dynamics Observatory or Atmospheric Imaging Assembly (SDO/AIA). Mini-dimmings are sometimes associated with wave-like brightening, called coronal mass ejections. Here, the sun full disk images with 171 Å wavelenght, cadence of 2.5, and 0.6 arcsec cell size, were taken on 3 March ...
متن کاملThe Role of Magnetic Reconnection in Solar Activity
We argue that magnetic reconnection plays the determining role in many of the various manifestations of solar activity. In particular, it is the trigger mechanism for the most energetic of solar events, coronal mass ejections and eruptive flares. We propose that in order to obtain explosive eruptions, magnetic reconnection in the corona must have an “on-off” nature, and show that reconnection i...
متن کاملExploring the Role of Magnetic Reconnection in Solar Eruptive Events
We summarize our recent progress in investigating the role of magnetic reconnection in solar eruptive events consisting of flares, Coronal Mass Ejections (CMEs), and/or Magnetic Clouds (MCs). The rate and total flux of magnetic reconnection in low-corona are inferred from flare observations and compared with kinematic properties and magnetic flux budget of erupting flux ropes. The results and t...
متن کاملA Comparative Study Between Eruptive X-class Flares Associated with Coronal Mass Ejections and Confined X-class Flares
Following the traditional naming of “eruptive flare” and “confined flares” but not implying a causal relationship between flare and coronal mass ejection (CME), we refer to the two kinds of large energetic phenomena occurring in the solar atmosphere as eruptive event and confined event, respectively: the former type refers to flares with associated CMEs, while the later type refers to flares wi...
متن کاملA Workflow-Oriented Approach to Propagation Models in Heliophysics
The Sun is responsible for the eruption of billions of tons of plasma and the generation of near light-speed particles that propagate throughout the solar system and beyond. If directed towards Earth, these events can be damaging to our tecnological infrastructure. Hence there is an effort to understand the cause of the eruptive events and how they propagate from Sun to Earth. However, the phys...
