摘要

Aims. We construct families of time-sequences of x-invariant magnetostatic equilibria which describe ideal quasi-static evolutionsdriven by stationary shearing motions imposed on a boundary. The change in the thermal pressure of the plasma is determined by imposing either an adiabatic, or an isothermal, or an isobaric, prescription.Methods. We start from a well known family of linear force-free fields, on which we effect simple transforms. Results. In either case, the magnetic field and the pressure are expressed analytically as functions of space and time. The field is found to suffer an indefinite expansion, with a decrease to zero of the pressure in the adiabatic and isothermal cases, and to eventually open. Moreover, the configurations forming any sequence are shown to be linearly stable with respect to x-invariant perturbations.
