类木行星作为引力波的共同探测器
Jovian planets as co-detectors of gravitational waves
摘要:
恒星中的声波振荡可以由引力波驱动。然而,目前使用日震学数据进行探测是不可行的,因为不可能理清源自太阳本身的不确定驱动因素。我们在这里指出,任何这样的波也会以类似的$and$ $way$影响木星和土星;毕竟,它们大多是像太阳一样的气体球,只是小一个数量级。因此,类似于粒子物理实验中的重合探测概念,对这三个物体中任何两个的相同振荡模式的测量声速的时间关联函数的评估将消除(独立的)内部效应;并且观察该关联函数中的峰值将等同于探测到引力波。有一个(轻微)的可能性,这种检测已经发生。
英文摘要:
Acoustic oscillations in stars can be driven by gravitational waves. However, at present it is not feasible to use the helioseismology data for their detection, since it is impossible to disentangle the uncertain driving contributions originating in the Sun itself. We here point out that any such wave will affect also Jupiter and Saturn in a similar $and$ $coordinated$ $way$; after all, they are mostly spheres of gas like the Sun, only one order of magnitude smaller. Hence, akin to the concept of coincidence detection in particle physics experiments, evaluation of the time-correlation function of the measured acoustic velocities of the same mode of oscillation of any two of these three objects will eliminate the (independent) internal effects; and observation of a peak in that correlation function will be tantamount to detection of a gravitational wave. There is a (slight) possibility that such detection has already occured.
