Journal ArticleDOI
Formation and eruption of solar prominences
TL;DR: In this paper, a model for the magnetic field associated with solar prominences is considered, and it is shown that flux cancellation at the neutral line of a sheared magnetic arcade leads to the formation of helical field lines which are capable, in principle, of supporting prominence plasma.
Journal ArticleDOI
Chromospheric Damping of Alfvén Waves
TL;DR: In this paper, the authors analyzed the damping time of a given wave frequency propagating through model chromospheres of various solar structures such as active region plage, quiet sun, and the penumbra and umbra of sunspots.
Journal ArticleDOI
Origin and Evolution of Filament-Prominence Systems
TL;DR: In this article, a head-to-tail linkage model for the formation, evolution, and eruption of solar filaments is presented, based on the observation that filaments form exclusively in filament channels with no apparent magnetic connections above the polarity inversion line.
Journal ArticleDOI
A circuit model for filament eruptions and two-ribbon flares
Petrus C. Martens,N. P. M. Kuin +1 more
TL;DR: In this paper, a circuit model for solar filament eruptions and two-ribbon flares was derived, where the filament is approximated as a line current and the current sheet as infinitely thin.
Journal ArticleDOI
The unusual minimum of sunspot cycle 23 caused by meridional plasma flow variations
Dibyendu Nandy,Andrés Muñoz-Jaramillo,Andrés Muñoz-Jaramillo,Petrus C. Martens,Petrus C. Martens +4 more
TL;DR: Results from kinematic dynamo simulations are reported which demonstrate that a fast meridional flow in the first half of a cycle, followed by a slowerFlow in the second half, reproduces both characteristics of the minimum of sunspot cycle 23 and predicts that, in general, very deep minima are associated with weak polar fields.
