NUMERICAL SIMULATIONS OF THE STABILITY OF A THICK GASEOUS DISK WITH MAGNETIC FIELD

摘要

Se estudia la respuesta a perturbaciones de un disco galactico gaseoso grueso, con campo magnetico y rayos cosmicos. Se exploran diferentes modelos para la capa de gas en equilibrio hidrostatico con el campo gravitacional local. Las perturbaciones simulan eventos de gran amplitud, tales como el impacto de nubes - masivas con el disco galactico. Presentamos resultados preliminares para una serie de experimentos sobre la estabilidad del disco con y sin campo magnetico. We study the response to perturbations of a thick galactic disk of gas, with a magnetic field and cosmic rays. Different models for the layer in hydrostatic equilibrium with the local gravitational field are explored. The perturbations simulate large amplitude events, such as the impact of massive clouds with the galactic disk, We present preliminary results for a series of experiments on the stability of the layer with and without magnetic fields.
