Nonlinear evolution of Parker instability of isolated magnetic flux sheet and its application to emerging magnetic flux in the solar atmosphere.
Abstract
A two dimensional MHD code is used to study the nonlinear evolution of the Parker instability in isolated horizontal magnetic flux imbedded in (or below) the solar photosphere. It is found that the magnetic loop expands self-similarly in the nonlinear stage. Numerical results explain many features observed in emerging flux regions.
