| contents | MHD Stabiblity of a Solar Prominence Embedded in an External Vertical Magnetic Field J. Galindo Trejo Física, Astronomía y Matemáticas MHD: WAVES SUN:PROMINENCES SUN: OSCILLATIONS We examine the linear MHD-stability of a solar quiescent prominence describedby the two-dimensional model of Osherovich (1989). This equilibrium modeltakes into account explicitly the influence of an external vertical magnetic field sothat the prominence can be situated on the boundary between two regions of oppositemagnetic polarity. We analyze its stability against perturbations within idealMHD using a numerical method based on the Energy Principle of Bernstein et al.(1958). In our study specific cases of physical parameters observed in quiescentprominence are considered. For completeness we present as well results for otherparameters which may perhaps be applicable to solar-type stars. 2006 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57142109 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.42 |
