双星吸气中中子星激发的引力波

Gravitational waves from neutron star excitations in binary inspirals

A. Parisi, R. Sturani

摘要:

在混合中子星-黑洞系统的双星内旋背景下,研究了轨道运动对中子星振荡模的激发。我们研究了一般的偏心轨道,并表明潮汐相互作用可以激发的f-模式振荡的恒星通过计算的能量和角动量沉积到恒星的轨道运动潮汐力通过封闭形式的解析表达式。我们使用最近的微观核状态方程研究冷中子星的f-模式振荡,并计算它们对发射的引力波的影响。

英文摘要:

In the context of binary inspiral of mixed neutron star - black hole systems, we investigate the excitation of the neutron star oscillation modes by the orbital motion. We study generic eccentric orbits and show that tidal interaction can excite the f-mode oscillations of the star by computing the amount of energy and angular momentum deposited into the star by the orbital motion tidal forces via closed form analytic expressions. We study the f-mode oscillations of cold neutron stars using recent microscopic nuclear equations of state, and we compute their imprint into the emitted gravitational waves.
