由黑洞形成引发的标量 tsunami
Scalar Tsunamis from Black Hole Formation
AI总结：
本文研究了由黑洞形成引发的标量场释放，改进了广义相对论影响和初始场配置建模，发现能量释放量与简单估计相当，光谱有明显修正。
摘要：
恒星及其他宏观物体可能被潜在的大场配置包围，这些非常轻的标量场与普通物质耦合。如果恒星最终形成黑洞，例如通过超新星或中子星合并，源会消失，而场会被释放。在本文中，我们改进了先前对远距离场配置的估计，包括广义相对论的影响以及初始场配置的改进建模。释放的总能量通常与简单的平空间估计建议的量级相同。光谱受到明显修正。
英文摘要：
Stars and other macroscopic objects may be surrounded by potentially large field configurations of very light scalars coupled to ordinary matter. If the star ends in a black hole, e.g. via a supernova or a neutron star merger, the source vanishes, and the field is released. In this paper, we improve on previous estimates for the field configurations arriving at large distances by including the effects of general relativity and an improved modelling of the initial field configurations. The total amount of energy released is typically of the same order of magnitude as suggested by simple flat space estimates. The spectrum receives noticeable corrections.
