论文摘要
暗物质可以被天体物体捕获,并在其中心积聚,形成一个暗物质的核心,只要an灭速率很小或零,就可以塌陷到一个黑色的黑洞中。如果新生的黑洞足够大,它将生长以消耗恒星或行星。我们计算了太阳和地球中暗物质积累的速率,并利用它们的持续存在将新颖的限制放在高质量不对称的暗物质相互作用上。我们还识别和细节较少的破坏性特征:新形成的黑洞可能足够小,可以通过鹰辐射蒸发,从而导致从地球发出异常的热流,或者在可观察到的Icecube的Sun Sunement中微子中散发出异常的热量。后者的签名是全新的,我们发现它可能涵盖很大的参数空间区域,这些区域未通过任何其他方法探测。
Dark matter can be captured by celestial objects and accumulate at their centers, forming a core of dark matter that can collapse to a small black hole, provided that the annihilation rate is small or zero. If the nascent black hole is big enough, it will grow to consume the star or planet. We calculate the rate of dark matter accumulation in the Sun and Earth, and use their continued existence to place novel constraints on high mass asymmetric dark matter interactions. We also identify and detail less destructive signatures: a newly-formed black hole can be small enough to evaporate via Hawking radiation, resulting in an anomalous heat flow emanating from Earth, or in a flux of high-energy neutrinos from the Sun observable at IceCube. The latter signature is entirely new, and we find that it may cover large regions of parameter space that are not probed by any other method.
