On the Role of Magnetic Fields in an Erupting Solar Filament

Proceedings of the International Astronomical Union, 2019
AbstractA filament eruption may lead to a coronal mass ejection (CME), which is one of the main driving mechanisms of space weather. This work analyses a slow and flareless CME event associated with an erupting quiescent filament. By using the extreme ultraviolet images of the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory, we ...

Height of a solar filament before eruption

Astronomy Reports, 2013
The relationship between the height of a solar filament observed above the photosphere before the eruption on October 21, 2010, and the critical height of a stable equilibrium of magnetic flux ropes in the coronal magnetic field is analyzed. Data from the SDO, SOHO, and STEREO space observatories observing at different viewing angles makes it possible ...

Aspects of the Global MHD Equilibria and Filament Eruptions in the Solar Corona

Space Science Reviews, 2001
This is a review of several promising approaches for analyzing the accumulation and release of magnetic energy in filament eruptions and coronal mass ejections in the solar corona. The importance of the magnetic virial theorem for understanding the role of slowly changing boundary conditions in the photosphere is stressed.

A theory of filament eruptions before the impulsive phase of solar flares

Solar Physics, 1992
We present a theory of filament eruption before the impulsive phase of solar flares. We show that the upward motion of the magnetic X-point tracing the filament eruption begins several minutes before the impulsive phase of the flare, where the explosive magnetic reconnection starts at the X-point magnetic field configuration located under the filament.

Development of a filament eruption during a solar flare

2002
Using BBSO Hα images and TRACE data, we have studied a prominence eruption occurred on July 19th, 2000, in active region 9077, at the west limb of the Sun. We have followed the morphological evolution of the prominence several hours before its activation and during the eruption phase, in different atmospheric layers.
