双中子星的布居合成
Population synthesis of double neutron stars
摘要：
使用StarTrack二进制人口合成代码，我们在银河系中的双中子星的人口模型。我们包括一个详细的治疗过程中，如自旋下降和自旋的吸积事件，以及磁场衰减每个脉冲星的自旋演化。我们还模拟了双中子星的空间分布，包括它们的出生踢和随后的传播在银河系引力势。这个合成的脉冲星人口相比，观察到的样本的双中子星考虑到选择的影响，在无线电波段的检测，以确定最有可能的演化参数。利用这些参数，我们确定了由高频干涉仪LIGO和VIRGO在引力波中可探测到的双中子星双星的性质。特别地，我们讨论了啁啾质量和质量比的分布在样品中选择他们的无线电或引力波发射。
英文摘要：
Using the StarTrack binary population synthesis code we model the population of double neutron stars in the Galaxy. We include a detailed treatment of the spin evolution of each pulsar due to processes such as spin-down and spin-up during accretion events as well as magnetic field decay. We also model the spatial distribution of double neutron stars by including their natal kicks and subsequent propagation in the Galactic gravitational potential. This synthetic pulsar population is compared to the observed sample of double neutron stars taking into account the selection effects of detection in the radio band, to determine the most likely evolutionary parameters. With these parameters we determine the properties of the double neutron star binaries detectable in gravitational waves by the high frequency interferometers LIGO and VIRGO. In particular, we discuss the distributions of chirp masses and mass ratios in samples selected by their radio or gravitational wave emission.
