The eruption of a small filament in the quiet Sun

Astrophysics and Space Science, 2008
We analyzed multi-wavelength observations of the eruption of a small-scale filament on the quiet Sun. The filament first became thicker, then broke into two, and eventually underwent a partial eruption with possible rotating motion. The eruption was followed by a small flare with three bright kernels on either side of the eruptive section in Hα and a ...

The formation of radio brightening bands near cool filaments on the Sun

Astronomy Letters, 2002
We analyze the spatial distribution of the intensity of radio emission from a cool filament in terms of the generalized Kippenhahn-Schluter model. Based on a numerical calculation of the centimeter radio emission and using the temperature transition layer model by Anzer and Heinzel (1999), we show that two symmetric brightening bands must be observed ...

Destabilization, interaction, and eruption of filaments on the sun and associated phenomena

Geomagnetism and Aeronomy, 2013
A brief overview of the observation results of filament interactions on the Sun both from the Earth and from space at the TRACE, SOHO, STEREO, Hinode, and Yohkoh stations in white light, Hα, extreme UV (EUV), X rays, and a radio range is presented. Various filament collision cases, where filaments merge (or do not merge) or change their forms as a ...

Rotating twisted filaments buoyancy: comparison between the convective region of the sun and the edge of a tokamak plasma

Plasma Physics and Controlled Fusion, 2008
The filament state of a magnetic field is the usual way for plasmas to avoid magnetic inhibition of convective overturning. However, it requires dynamo conversion of kinetic into magnetic energy and is therefore often associated with a plasma velocity shear layer.

Large-scale phenomena on the Sun associated with the eruption of filaments outside active regions: the event of September 12, 1999

Astronomy Reports, 2009
The event of September 12, 1999 is used to analyze large-scale disturbances associated with coronal mass ejections during the eruption of filaments outside active regions. The analysis is based on Hα filtergrams, EUV and soft X-ray images, and coronograph data.

Reconstruction of the Filament Properties, Based on Centenarian Daily Observations of the Sun in H_α Line

Proceedings of the International Astronomical Union, 2017
AbstractPreliminary results of distinguishing solar filaments on daily observation data at the Hα spectral line of the Kodaikanal Solar Observatory (1912-2002) are presented.To distinguish the boundaries of solar filaments, methods have been developed, based on automatic procedures for distinguishing low-contrast objects on the solar disk as well as on
