旋转陀螺周围的精确相对论磁化晕

Exact Relativistic Magnetized halos around Rotating Disks

Antonio C. Gutiérrez-Piñeres, Abraão J. S. Capistrano

摘要:

本文给出了被磁化物质晕包围的旋转圆盘的精确相对论处理。晕和盘的特征用一般流体的分布能量动量张量的正则形式来描述。所有相关的量和度规势和电磁势都只由任意的调和函数精确地确定。例如,使用广义Kuzmin盘势。所得到的解是渐近平坦的,并且满足所有的能量条件。此外,还描述了带电粒子在晕上的运动。据我们所知,这是第一个解析描述旋转圆盘磁化晕的相对论模型。

英文摘要:

The exact relativistic treatment of a rotating disk surrounded by a magnetized material halo is presented. The features of the halo and disk are described by the distributional energy-momentum tensor of a general fluid in canonical form. All the relevant quantities and the metric and electromagnetic potentials are exactly determined by an arbitrary harmonic function only. For instance, the generalized Kuzmin-disk potential is used. The particular class of solutions obtained is asymptotically flat and satisfies all the energy conditions. Moreover, the motion of a charged particle on the halo is described. As far as we know, this is the first relativistic model describing analytically the magnetized halo of a rotating disk.
