Abstract
We examine the linear MHD-stability of a solar quiescent prominence described by the two-dimensional model of Osherovich (1989). This equilibrium model takes into account explicitly the influence of an external vertical magnetic field so that the prominence can be situated on the boundary between two regions of opposite magnetic polarity. We analyze its stability against perturbations within ideal MHD using a numerical method based on the Energy Principle of Bernstein et.1958). In our study specific cases of physical parameters observed in quiescent prominence are considered. For completeness we present as well results for other parameters which may perhaps be applicable to solar-type stars.
