- Title
- Modelling of entire prominences with their multiple fine structures: the 3D Whole-Prominence Fine Structure models
- Abstract
-
We will present the 3D Whole-Prominence Fine Structure (WPFS) models which combine 3D magnetic field configurations of entire prominences with a detailed description of the prominence plasma. The plasma is located in magnetic dips in hydrostatic equilibrium and is distributed along hundreds of fine structures within the 3D magnetic field configurations. The prominence plasma has realistic density and temperature distributions including the prominence-corona transition region. Thanks to this, the 3D WPFS models provide us with a representation of prominences (and filaments) with a complexity that begins to approach real prominences. We have developed two WPFS models – the first by Gunar & Mackay (2015) and the second by Gunar et al. (2018). These models allow us to investigate links between the distribution of the prominence plasma, configuration of its magnetic field and observations of the prominence/filament fine structures obtained in UV/EUV, optical and radio domains from various vantage points. The models thus serve as a virtual laboratory that helps us to test different physical properties of prominences.
We will present the basic building blocks of our models and highlight some of the results obtained by the 3D prominence modelling. We will, for example, investigate the evolution of prominences/filaments in response to changes in the underlying photospheric flux distribution. We will also explore the role of projection effects and visibility of prominence fine structures in our understanding of prominences. In addition, we will look at simulations of prominences and filaments in ALMA wavelengths. - Facilitator
