A Model of Homologous Confined and Ejective Eruptions Involving Kink Instability and Flux Cancellation
Alshaimaa Hassanin, Bernhard Kliem, Norbert Seehafer +1
In this study, we model a sequence of a confined and a full eruption, employing the relaxed end state of the confined eruption of a kink-unstable flux rope as the initial condition…
Helicity shedding by flux rope ejection
B. Kliem, N. Seehafer
We quantitatively address the conjecture that magnetic helicity must be shed from the Sun by eruptions launching coronal mass ejections in order to limit its accumulation in each h…
Helical Kink Instability in the confined Solar Eruption on 2002 May 27
Alshaimaa Hassanin, Bernhard Kliem, Norbert Seehafer
This paper presents an improved MHD modeling of the confined filament eruption in solar active region NOAA~9957 on 2002 May~27 by extending the parametric studies of the event in T…
An advective solar-type dynamo without the alpha effect
N. Seehafer, V. V. Pipin
Context: Most solar and stellar dynamo models use the alpha-Omega scenario where the magnetic field is generated by the interplay between differential rotation (the Omega effect) a…
