Successive filament eruptions within one solar breakout event [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractThe magnetic breakout model has been widely used to explain solar eruptive activities. Here, we apply it to explain successive filament eruptions occurred in a quadrupolar magnetic source region. Based on the high temporal and spatial resolution, multi-wavelengths observations taken by the Atmospheric Imaging Assembly (AIA) on board the Solar ...

Recent Observations of the Early Stage of Solar Eruptions [PDF]
, 2008 We examine the onset of two solar eruptions, using data from Hinode STEREO, TRACE, and SOHO, and other sources. One eruption occurred on 2007 March 2, and the other occurred on 2007 May 20.

Filament Eruptions, Jets, and Space Weather [PDF]
, 2013 Previously, from chromospheric H alpha and coronal Xray movies of the Sun's polar coronal holes, it was found that nearly all coronal jets (greater than 90%) are one or the other of two roughly equally common different kinds, different in how they erupt:

The Noneruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
The Astrophysical JournalThe unpredictability of solar filament eruptions presents major challenges for forecasting space weather, since such eruptions frequently drive coronal mass ejections that impact the heliosphere.

Investigating an Erupting Metric-decimetric Radio Depression and Its Physical Origin
The Astrophysical JournalWe present direct metric-decimetric radio imaging observations of a fascinating quiescent filament eruption on 2024 March 17 using data from the DAocheng Radio Telescope, with a combination of the Solar Dynamics Observatory and the Chinese H α Solar ...

A type II radio burst associated with solar filament–filament interaction [PDF]
Aims. Solar radio type II bursts are often associated with coronal shocks driven by solar eruptions. In this study, we report a type II burst associated with filament–filament interaction. Methods.

Rotation of a Solar Jet Driven by Plasma Flow along Helical Magnetic Fields in an Active Region
The Astrophysical JournalSolar jets, collimated plasma ejections driven by magnetic reconnection, play a vital role in energy transport and coronal heating. While rotational motions in jets are often attributed to magnetic field untwisting, alternative explanatory mechanisms ...

Stereoscopic Analysis of 19 May and 31 Aug 2007 Filament Eruptions [PDF]
, 2008 The presentation outline includes results from stereoscopic analysis of SECCHI/EUVI data for 19 May 2007 filament eruption, including the determined 3D trajectory of erupting filament, strong evidence for reconnection below erupting filament as ...

The Eruptive Duality of a Filament on 2023 April 21
The Astrophysical JournalHere we study a filament eruption on 2023 April 21. The filament was composed of two segments, named S1 and S2. Initially, the brightening and bidirectionally plasmoid flows appeared inside S1, and then the west part of S1 (WS1) experienced rapid rising ...
