Closed Magnetic Structures in the Chromosphere and in the Transition Region
Abstract
Using simultaneous observations of the same solar regions in the lines Hα and CIV 1548 Å, we have derived schematic models of closed magnetic lines from dynamical constraints. We conclude that the magnetic loops are closed at higher levels above facular than above non-facular regions. This result remains valid whatever are the assumed density models and even if we take into account the 3 min oscillations. The center-to-limb behaviour is well predicted by taking into account the relative opacity in chromosphere and transition region.
