Key Signatures of Prominence Materials and Category of Cold Materials Identified by Random Forest Classifier

open access: yesThe Astrophysical Journal Supplement Series, 2023
The origin of cold materials identified by different criteria is unclear. They are highly suspected to be erupted prominences. However, some cold materials defined by charge depletion exist in both quiet solar wind and interplanetary coronal mass ...

Dissipative instability in partially ionised prominence plasmas [PDF]

open access: yes, 2015
We investigate the nature of dissipative instability at the boundary (seen here as tangential discontinuity) between the viscous corona and the partially ionised prominence plasma in the incompressible limit.

Effect of motions in prominences on the helium resonance lines in the extreme ultraviolet [PDF]

open access: yes, 2006
<b>Context</b>: Extreme ultraviolet resonance lines of neutral and ionised helium observed in prominences are difficult to interpret as the prominence plasma is optically thick at these wavelengths. If mass motions are taking place, as is the

Automatic detection of limb prominences in 304 A EUV images [PDF]

open access: yes, 2009
A new algorithm for automatic detection of prominences on the solar limb in 304 A EUV images is presented, and results of its application to SOHO/EIT data discussed.

High-altitude Spider-type Prominence above the Magnetic Null Point

open access: yesThe Astrophysical Journal, 2023
Rather unique observations of a high-altitude spider-type prominence in 2023 February are presented. The prominence or corresponding filament on the disk was not visible all the time but could appear and disappear in the course of a particular day ...

An analytical model of prominence dynamics

open access: yes, 2017
Solar prominences are magnetic structures incarcerating cool and dense gas in an otherwise hot solar corona. Prominences can be categorized as quiescent and active.

Solar Prominence Interactions

open access: yesThe Astrophysical Journal, 2005
We report numerical simulations of the formation, interaction, and magnetic reconnection between pairs of solar prominences within the sheared-arcade model. Our experiments consider the four possible basic combinations of chiralities (identical or opposite) and axial magnetic fields (aligned or opposed) between the participating prominences.

The Structure of Coronal Mass Ejections Recorded by the K-Coronagraph at Mauna Loa Solar Observatory

open access: yesThe Astrophysical Journal Letters, 2023
Previous survey studies reported that coronal mass ejections (CMEs) can exhibit various structures in white-light coronagraphs, and ∼30% of them have the typical three-part feature in the high corona (e.g., 2–6 R _⊙ ), which has been taken as the ...
