Confined and Ejective Eruptions of Kink-unstable Flux Ropes
Confined and Ejective Eruptions of Kink-unstable Flux Ropes
The ideal helical kink instability of a force-free coronal magnetic flux rope, anchored in the photosphere, is studied as a model for solar eruptions. Using the flux rope model of Titov and Démoulin as the initial condition in MHD simulations, both the development of helical shape and the rise profile …
