伽玛暴旋进引擎产生的引力波

Gravitational waves from precessing engines in GRBs

Gustavo E. Romero, Matías M. Reynoso, Hugo R. Christiansen

摘要:

在伽马射线暴中心的瞬态吸积盘的框架下,我们计算了Lense-Thirring进动的可能周期。接下来,我们评估了与这种动力学设置相关的假定引力波。假设一个磁盘射流系统的伽马射线发射的特征时间剖面,我们得到的光变曲线呈现出类似于一些GRB事件中报道的时间微观结构。在调整了两个特定伽玛暴的参数后,我们评估了这个吸积盘进动产生的引力波的可探测性。最后,我们的分析表明,一些伽玛暴是可能的探测与先进的LIGO。

英文摘要:

In the framework of a transient accretion disk at the core of a gamma-ray burst we compute possible periods of Lense-Thirring precession. Next, we evaluate the putative gravitational waves associated with such dynamical setup. Assuming a characteristic time-profile for the gamma-ray emission of a disk-jet system, we obtain light-curves presenting a time microstructure similar to that reported in some GRB events. After adjustment of the parameters out of two specific GRBs we evaluate the detectability of the gravitational waves produced by the precession of this accretion disk. As a conclusion, our analysis shows that some GRBs are likely to be probed with Advanced LIGO.
