广义相对论等离子体中波传播的能量耗散
Energy dissipation in wave propagation in general relativistic plasma
摘要:
本文根据作者最近的一次通讯,研究了广义相对论中暴胀背景下磁流体动力学波的能量耗散问题。据发现,扩大的背景介绍了一种拖曳力的传播波,使不同的牛顿的情况下,能量得到耗散,因为它的进展。然而,这种没有特殊相对论性类似物的能量损失在本质上不像弹性波那样是机械的。它还发现,能量损失是模型依赖的,也取决于维数。
英文摘要:
Based on a recent communication by the present authors the question of energy dissipation in magneto hydrodynamical waves in an inflating background in general relativity is examined. It is found that the expanding background introduces a sort of dragging force on the propagating wave such that unlike the Newtonnian case energy gets dissipated as it progresses. This loss in energy having no special relativistic analogue is, however, not mechanical in nature as in elastic wave. It is also found that the energy loss is model dependent and also depends on the number of dimensions.
