论文摘要
轴恒星可以用中子星形成二进制。鉴于单个中子恒星表现出极强的外部磁场，因此在这些二进制中，轴可能会大量转化为光子。由于中子恒星旋转和轴心恒星旋流，光子发射被双重调节，从而产生了独特的发现信号。中子恒星和斧头笼罩的黑洞之间的二进制文件也会产生类似的特征。令人鼓舞的是，对于某些参数区域而言，发现这种二进制物在正在进行的和即将进行的实验范围内（例如，五百米孔镜球形望远镜和未来的平方公里阵列）。因此，它们提供了一个有希望的天文学实验室，用于检测斧头和斧头暗物质。
Axion stars could form binaries with neutron stars. Given the extremely strong external magnetic field exhibited by individual neutron stars, there can be a substantial conversion of axions to photons in these binaries. The photon emission is doubly modulated due to the neutron star spinning and the axion star orbiting, yielding a unique discovery signal. Similar features are also generated in binaries between a neutron star and an axion-clouded black hole. Encouragingly, such binaries are found to be within the reach of ongoing and upcoming experiments (e.g., the Five hundred meter Aperture Spherical Telescope and the future Square Kilometer Array) for certain parameter regions. They thus provide a promising astronomical laboratory for detecting axions and axion dark matter.
