旋转黑洞场中的应变和轴向外流
Strains and axial outflows in the field of a rotating black hole
摘要：
我们研究了一个最初的球形束的加速粒子沿轨道平行于对称轴的旋转黑洞发射的行为。我们发现，在适当的条件下，曲率和惯性应变竞争模型的轴向流出的物质有助于产生射流状结构的形状。当然，这是一种纯粹的运动学效应，它本身并不能解释形成喷流的物理过程。在我们的分析中，外尔张量的电磁部分的性质在克尔时空中沿着对称轴是洛伦兹不变的，这一性质起着至关重要的作用。
英文摘要：
We study the behaviour of an initially spherical bunch of accelerated particles emitted along trajectories parallel to the symmetry axis of a rotating black hole. We find that, under suitable conditions, curvature and inertial strains compete to model the shape of axial outflows of matter contributing to generate jet-like structures. This is of course a purely kinematical effect which does not account by itself for physical processes underlying the formation of jets. In our analysis a crucial role is played by a property of the electric and magnetic part of the Weyl tensor to be Lorentz-invariant boosting along the axis of symmetry in Kerr spacetime.
