克尔背景下的惠勒方程与天体物理喷流准直

Wheeler equation in Kerr background and astrophysical jet collimation

X H Zheng, J X Zheng

摘要:

惠勒方程在克尔背景下有一个扩展。它有一个精确的解决方案,代表了运行谐波在龟坐标。这种波以一种新的方式模拟了天体物理学上的喷流,因为它沿着时空旋转的轴准直,当旋转加快时,这种准直会越来越紧密。该模型赞同以前的数值计算工作,建议内准直喷燃料的彭罗斯样的过程。它也赞同以前的理论工作作物单向运行波的精确解Heun的方程。

英文摘要:

The Wheeler equation has an extension in the Kerr background. It has an exact solution representing a running harmonic wave in the tortoise coordinate. The wave models astrophysical jets in a new light because it collimates along the axis of spacetime rotation, increasingly tightly when rotation quickens. The model endorses a previous numerical work suggesting intrinsic collimation of jet fuelled by a Penrose-like process. It also endorses a previous theoretical work to crop one-way running waves from the exact solutions to Heun's equation.
