摘要

在这项工作中，我们研究了其他工作产生的（\ell \）玻色子星的正面碰撞，它们是暗物质紧凑天体的潜在候选者。我们首先回顾了这些恒星的一般性质和特征，利用先前研究的结果来分析这类碰撞产生的引力波信号。考虑到潜在事件的最大距离为 100 Mpc，我们确定了这些恒星的标量场质量和频率范围，从而使引力波能够被当前的引力波观测站探测到。得到的标量场质量范围是（m_\phi \,c^2 \in [10^{-15}, 10^{-10}]\) eV。此外，我们还对得到的信号进行处理，生成模拟的天文台图像，突出它们与黑洞碰撞产生的图像的异同。

On the detectability of gravitational waves emitted from head-on collisions of $\ell $-boson stars

In this work, we examine head-on collisions, produced by other work, of $\ell $-boson stars, potential candidates for dark matter compact objects. We begin with a review of the general properties and features of these stars, leveraging results from prior studies to analyze the gravitational wave signals generated by such collisions. Considering a maximum distance of 100 Mpc for potential events, we identify the range of scalar field masses and frequencies for these stars that would render the gravitational waves detectable by current gravitational wave observatories. The ranges obtained for the scalar field masses are $m_\phi \,c^2 \in [10^{-15}, 10^{-10}]$ eV. Additionally, we process the resulting signals to generate simulated observatory images, highlighting their similarities and differences compared to those produced by black hole collisions.
