Solar prominences: theory and models [PDF]

open access: yesLiving Reviews in Solar Physics, 2018
Magnetic fields suspend the relatively cool material of solar prominences in an otherwise hot corona. A comprehensive understanding of solar prominences ultimately requires complex and dynamic models, constrained and validated by observations spanning ...

Solar Prominences: Observations [PDF]

open access: yesLiving 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 ...

Solar Prominence Modelling and Plasma Diagnostics at ALMA Wavelengths. [PDF]

open access: yesSol Phys, 2017
Our aim is to test potential solar prominence plasma diagnostics as obtained with the new solar capability of the Atacama Large Millimeter / submillimeter Array (ALMA).

Prominence oscillations

open access: yesLiving Reviews in Solar Physics, 2018
Prominences are intriguing, but poorly understood, magnetic structures of the solar corona. The dynamics of solar prominences has been the subject of a large number of studies, and of particular interest is the study of prominence oscillations.

Time‐Latitude Distribution of Prominences for 10 Solar Cycles: A Study Using Kodaikanal, Meudon, and Kanzelhohe Data

open access: yesEarth and Space Science, 2020
Solar prominences are structures of importance because of their role in polar field reversal. We study the long‐term variation of the time latitude distribution of solar prominences in this article.

Physics of Solar Prominences: II - Magnetic Structure and Dynamics

open access: yesSpace Science Reviews, 2010
Observations 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 dynamics of ...

Rediscovering the observations of solar prominences from 1906 to 1957 recorded at the Madrid Astronomical Observatory

open access: yesJournal of Space Weather and Space Climate, 2023
The Madrid Astronomical Observatory implemented a solar observation program from 1876 to 1986. In addition to sunspots, the observers at this observatory recorded other solar features such as prominences.

Solar prominences [PDF]

open access: yesProceedings 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 ...

Solar prominence polarimetry [PDF]

open access: yesAstronomy & 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.
