GRB中央引擎的一种新模型

Toward a New Model of the Central Engine of GRB

P. P. Fiziev, D. R. Staicova

摘要:

我们提出了新的发展的简单模型的中央引擎的伽玛暴,最近提出的。该模型是基于最小的假设:一些旋转的紧凑的相对论性物体的中心和稳定的扰动,其旋转引力场,描述Teukolsky主方程。我们表明,使用非标准的多项式解的角度Teukolsky方程,我们可以描述形成的准直射流的各种形式。首次建立了Teukolsky方程纯真空黑洞喷流解的类超辐射频率虚部的出现。

英文摘要:

We present new developments of the simple model of the central engine of GRB, proposed recently. The model is based on minimal assumptions: some rotating compact relativistic object at the center and stable perturbations of its rotating gravitational field, described by Teukolsky Master Equation. We show that using nonstandard polynomial solutions to the angular Teukolsky equation we can describe the formation of collimated jets of various forms. Appearance of imaginary part of the superradiance-like frequency is established for the first time for pure vacuum black hole jet solutions of Teukolsky equation.
