Solar Prominences: Observations [PDF]
Living Reviews in Solar Physics, 2014 Solar prominences are one of the most common features of the solar atmosphere. They are found in the corona but they are one hundred times cooler and denser than the coronal material, indicating that they are thermally and pressure isolated from the surrounding environment.

, 2021 Abstract Solar prominences (or filaments) are cool dense regions of plasma that exist within the solar corona. Their existence is due to magnetic fields that support the dense plasma against gravity and insulate it from the surrounding hot coronal plasma.

Proceedings of the International Astronomical Union, 2008 AbstractSolar filaments (or prominences) are magnetic structures in the corona. They can be represented by twisted flux ropes in a bipolar magnetic environment. In such models, the dipped field lines of the flux rope carry the filament material and parasitic polarities in the filament channel are responsible for the existence of the lateral feet of ...

Physics of Solar Prominences: II—Magnetic Structure and Dynamics
Space Science Reviews, 2010 International audienceObservations and models of solar prominences are reviewed. We focus on non-eruptive prominences, and describe recent progress in four areas of prominence research: (1) magnetic structure deduced from observations and models, (2) the

Wavefront sensing and adaptive optics for solar prominences
, 2018 We explore the feasibility of adaptive optics for observations of prominences off the solar limb. We installed a wavefront sensor prototype on the GST at the Big Bear Solar Observatory.

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.

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
