先进探测器时代孤立星系中子星的连续引力波

Continuous Gravitational Waves from Isolated Galactic Neutron Stars in the Advanced Detector Era

Leslie Wade, Xavier Siemens, David L. Kaplan, Benjamin Knispel, Bruce Allen

摘要:

我们考虑一个孤立的银河系中子星的模拟人口。每颗中子星的旋转频率都是通过电磁波和引力波辐射的结合而演变的。磁场强度决定了偶极辐射,而椭圆率(中子星变形的量度)决定了引力波辐射。通过分析和数值方法,我们评估银河系中子星人口的可探测性和约束银河系中子星的磁场强度和椭圆度参数空间有或没有直接的引力波检测。虽然我们的模拟人口是原始的,这项工作建立了一个框架,未来的努力可以进行。

英文摘要:

We consider a simulated population of isolated Galactic neutron stars. The rotational frequency of each neutron star evolves through a combination of electromagnetic and gravitational wave emission. The magnetic field strength dictates the dipolar emission, and the ellipticity (a measure of a neutron star's deformation) dictates the gravitational wave emission. Through both analytic and numerical means, we assess the detectability of the Galactic neutron star population and bound the magnetic field strength and ellipticity parameter space of Galactic neutron stars with or without a direct gravitational wave detection. While our simulated population is primitive, this work establishes a framework by which future efforts can be conducted.
