La stabilité d'une surface chargée d'un plasma poussiéreux magnéto-radiatif est étudiée. Il est démontré que pour une condition particulière, la surface peut devenir instable grâce à deux mécanismes différents, l'un est lorsque la surface est chargée, tandis que l'autre se produit en raison des instabilités de dissipation causées par le flux d'énergie de rayonnement. Dans l'approximation linéaire, une relation de dispersion générale est dérivée, en tenant compte de l'effet magnéto-radiatif, de la charge de surface et de la gravité. L'importance du rayonnement thermique sur l'instabilité du jean est discutée pour un plasma poussiéreux magnétisé avec des effets gravitaionnels. Les équations MHD fluides sont développées en supposant que l'entropie de chaque sous-système de plasma est conservée, lorsque la température des espèces de plasma est non relativiste. La relation de dispersion, dans ce cas, montre que le rayonnement thermique aide à stabiliser l'instabilité des jeans. Il est démontré que le plasma est stable dans certaines gammes de longueurs d'onde. Le champ magnétique stabilise l'instabilité du jean lorsque l'onde se propage à travers le champ magnétique. Cependant, pour la propagation oblique, on voit que le champ magnétique ne stabilise pas l'instabilité du jean.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The stability of a charged surface of a magneto-radiative dusty plasma is investigated. It is shown that for a particular condition the surface can become unstable through two different mechanisms, one is when the surface is charged, while the other arises due to dissipation instabilities caused by the radiation energy flux. In the linear approximation, a general dispersion relation is derived, taking into account magneto -radiative effect, surface charge and gravity.The importance of thermal radiation on the Jeans instability is discussed for a magnetized dusty plasma with gravitaional effects. The one fluid MHD equations are developed by assuming that the entropy of each subsystem of plasma is conserved, when the temperature of plasma species is nonrelativistic. The dispersion relation, in this case shows that thermal radiation helps to stabilize Jeans instability. It is shown that the plasma is stable in certain range of wavelengths. The magnetic field stabilizes Jeans instability when the wave propagates across the magnetic field. However, for oblique propagation it is seen that the magnetic field does not stabilize Jeans instability. 88 pp. Englisch. N° de réf. du vendeur 9783639764635
