Asymmetric Dark Stars, i.e. compact objects formed from the collapse of asymmetric dark matter could potentially produce a detectable photon flux if dark matter particles self-interact via dark photons that kinetically mix with ordinary photons. The morphology of the emitted spectrum is significantly different and therefore distinguishable from a typical black-body one. Given the above and the fact that asymmetric dark stars can have masses outside the range of neutron stars, the detection of such a spectrum can be considered as a smoking gun signature for the existence of these exotic stars.

不对称暗星的光子光谱

非对称暗星，即由非对称暗物质坍缩形成的致密物体，如果暗物质粒子通过与普通光子动力学混合的暗光子进行自相互作用，则可能会产生可检测的光子通量。发射光谱的形态显着不同，因此可以与典型的黑体光谱区分开来。鉴于上述情况以及不对称暗星的质量可能超出中子星范围这一事实，检测到这样的光谱可以被视为这些奇异恒星存在的确凿证据。
