Forming prominences accounting for partial ionisation effects
V. Jerčić, B. Popescu Braileanu, R. Keppens
One of the most striking structures in the solar atmosphere are prominences, predominantly coronal structures, with thermodynamic conditions that vary from chromospheric internally…
Spectral Characteristics of a Rotating Solar Prominence in Multiple Wavelengths
A. G. M. Pietrow, V. Liakh, C. M. J. Osborne +2
We present synthetic spectra corresponding to a 2.5D magnetohydrodynamical simulation of a rotating prominence in the Ca II 8542 Å, H, Ca II K, Mg II k, Ly , and Ly lines…
Prominence and coronal rain formation by steady versus stochastic heating and how we can relate it to observations
V. Jerčić, J. M. Jenkins, R. Keppens
Prominences and coronal rain are two forms of coronal condensations for which we still lack satisfactory details on the formation pathways and conditions under which the two come t…
Two-fluid reconnection jets in a gravitationally stratified atmosphere
B. Popescu Braileanu, R. Keppens
The density decreases exponentially with height in the solar gravitationally stratified atmosphere, therefore the collisional coupling between the ionized plasma and the neutrals a…
1.5D NLTE spectral synthesis of a 3D filament/prominence simulation
J. M. Jenkins, C. M. J. Osborne, R. Keppens
Aims. We here demonstrate how the recently developed Lightweaver framework makes non-LTE (NLTE) spectral synthesis feasible on a new 3D ab-initio magnetohydrodynamic (MHD) filament…
The influence of flux rope heating models on solar prominence formation
N. Brughmans, J. M. Jenkins, R. Keppens
Aims. We begin by exploring the influence of two classes of commonly adopted heating models on the formation behaviour of solar prominences. These models consider either an exponen…
Solar prominences: 'double, double ... boil and bubble'
Rony Keppens, Chun Xia, Oliver Porth
Observations revealed rich dynamics within prominences, the cool 10,000 K, macroscopic (sizes of order 100 Mm) "clouds" in the million degree solar corona. Even quiescent prominenc…
