This Letter considers stellar core collapse in massive scalar-tensor theories of gravity. The presence of a mass term for the scalar field allows for dramatic increases in the radiated gravitational wave signal. There are several potential smoking gun signatures of a departure from general relativity associated with this process. These signatures could show up within existing LIGO-Virgo searches.
这封信探讨了在大量标量-张量引力理论中的恒星核心坍缩。标量场质量项的存在使得辐射引力波信号急剧增加。与这个过程相关的、偏离广义相对论的情况有几个潜在的明显迹象。这些迹象可能会在现有的激光干涉引力波天文台(LIGO)-处女座(Virgo)探测器搜索范围内显现出来。
