Coupling Photosphere and Corona: Linear and Turbulent Regimes
Coupling Photosphere and Corona: Linear and Turbulent Regimes
In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction effect of the corona on the photosphere, and invalidating the line-tying approximation. We consider here successively the effect of …
