The evolution of twisted coronal loops

✍ J. A. Robertson; A. W. Hood; R. M. Lothian 📂 Article 📅 1992 🏛 Springer 🌐 English ⚖ 815 KB

The evolution of coronal loops in response to slow photospheric twisting motions is investigated using a variety of methods. Firstly, by solving the time-dependent equations it is shown that the field essentially evolves through a sequence of 2-D equilibria with no evidence of rapid dynamic evolutio

The thermal statics of coronal loops

✍ B. Roberts; S. Frankenthal 📂 Article 📅 1980 🏛 Springer 🌐 English ⚖ 394 KB

The thermal statics of constant pressure coronal loops is discussed, with particular emphasis on non-equilibrium and scaling relations. An analytical solution showing explicitly the occurrence of non-equilibrium in radiation dominated loops is presented. In addition, the general scaling law for hot

The structure of coronal magnetic loops

We present here a model, based on observations, for the magnetic-field equilibrium of a cool coronal loop. The pressure structure, taken from the Harvard/Skylab EUV data, is used to modify the usual force-free-field form in quasi-cylindrical symmetry. The resulting field, which has the same directio

Loss of equilibrium in coronal loops

✍ R. M. Lothian; A. W. Hood 📂 Article 📅 1992 🏛 Springer 🌐 English ⚖ 617 KB

The loss of equilibrium in coronal magnetic field structures is a possible source of energy for coronal heating and solar flares. We investigate whether such a loss of equilibrium occurs when a coronal loop is progressively twisted by photospheric motions. In studies of 2-D cylindrical equilibria, l
