模拟环境黑洞合并的频率相关潮汐变形性

Modelling frequency-dependent tidal deformability for environmental black-hole mergers

Valerio De Luca, Andrea Maselli, Paolo Pani

摘要:

基于双星系统中黑洞由于潮汐相互作用而失去环境的事件,我们建立了一个潮汐变形能力介于相对低频的有限值(缀饰黑洞)和高频的零值(裸黑洞)之间的波形模型.然后,我们应用这个模型的例子的情况下,一个黑洞穿着超轻标量场和调查的潮汐勒夫数与爱因斯坦望远镜的可探测性。我们表明,潮汐变形模型的参数可以测量精度很高,提供了一个有用的工具,以了解动力学环境的影响发生在一个双系统的螺旋。

英文摘要:

Motivated by events in which black holes can lose their environment due to tidal interactions in a binary system, we develop a waveform model in which the tidal deformability interpolates between a finite value (dressed black hole) at relatively low frequency and a zero value (naked black hole) at high frequency. We then apply this model to the example case of a black hole dressed with an ultralight scalar field and investigate the detectability of the tidal Love number with the Einstein Telescope. We show that the parameters of the tidal deformability model could be measured with high accuracy, providing a useful tool to understand dynamical environmental effects taking place during the inspiral of a binary system.
