Diagnostics of active and eruptive prominences through hydrogen and helium lines modelling [PDF]

, 2008
In this study we show how hydrogen and helium lines modelling can be used to make a diagnostic of active and eruptive prominences. One motivation for this work is to identify the physical conditions during prominence activation and eruption. Hydrogen and

Analyses on Wassenius’s Report for Total Solar Eclipse in 1733: Quantifications of the Solar Radius and the Earliest Reported Prominences

The Astrophysical Journal
Total solar eclipses (TSEs) offer a unique opportunity to observe the solar atmosphere, detect limb phenomena, and accurately measure the solar radius.

Solar prominence polarimetry [PDF]

Astronomy & Astrophysics, 2003
We measure the resonance polarization in solar prominences in H α , H β and HeD 3 . A two-dimensional set-up with narrow-band filter, polarization analyzer and CCD camera is used to take prominence images in polarized light at high spatial resolution.

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

The 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 ...

Partially-erupting prominences: a comparison between observations and model-predicted observables [PDF]

, 2009
<p><b>Aims:</b> We investigate several partially-erupting prominences to study their relationship with other CME-associated phenomena and compare these observations with observables predicted by a model of partially-expelled-flux-ropes (

Equilibrium and eruption of solar coronal magnetic structures [PDF]

, 2014
In this thesis magnetostatic and thermal equilibria of several coronal magnetic structures are considered. A model is set up for the eruption of a prominence (modelled as a twisted flux tube) magnetically coupled to a coronal mass ejection (an ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.
