原初双黑洞合并前的自旋

Spins of primordial binary black holes before coalescence

Konstantin Postnov, Nikita Mitichkin

摘要:

原始恒星质量的黑洞,可能有助于暗物质和观察到的LIGO双星黑洞合并,预计出生时具有非常低的自旋。在这里,我们表明,吸积质量增益的原始黑洞二进制组件从周围的物质可能会导致显着的自旋的组件之前,提供高的初始轨道偏心率的合并。

英文摘要:

Primordial stellar-mass black holes, which may contribute to dark matter and to the observed LIGO binary black hole coalescences, are expected to be born with very low spins. Here we show that accretion mass gain by the components of a primordial black hole binary from the surrounding matter could lead to noticeable spins of the components prior to the coalescence provided high initial orbital eccentricities.
