GW150914黑洞的称重

Weighing The Black Holes Of GW150914

Yuan K. Ha

摘要:

我们通过准局域能量方法计算了GW 150914黑洞在其事件视界的质量,得到了71和57个太阳质量的值,而LIGO报告的渐近值分别为36和29个单位。为了克服黑洞周围巨大的负引力势能,并允许在合并过程中发射引力波,事件视界处的更高质量是强制性的。我们从视界质量估计了坍缩形成黑洞的恒星的初始质量,并得到了这些祖星的95和76太阳质量的令人印象深刻的值。

英文摘要:

We evaluate the mass of the black holes of GW150914 at their event horizons via quasi-local energy approach and obtain the values of 71 and 57 solar masses, compared to their asymptotic values of 36 and 29 units, respectively, as reported by LIGO. A higher mass at the event horizon is compulsory in order to overcome the huge negative gravitational potential energy surrounding the black holes and allow for the emission of gravitational waves during merging. We estimate the initial mass of the stars which collapsed to form the black holes from the horizon mass and obtain the impressive values of 95 and 76 solar masses for these progenitor stars.
