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.

暗物质可以被天体捕获并在其中心积累，形成暗物质核心，只要湮灭率很小或为零，就可以坍缩成一个小黑洞。如果新生的黑洞足够大，它就会长大以吞噬恒星或行星。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对高质量的不对称暗物质相互作用施加了新的限制。我们还确定并详细说明了破坏性较小的特征：新形成的黑洞可以小到足以通过霍金辐射蒸发，从而导致地球发出异常热流，或者在冰立方观测到来自太阳的高能中微子通量. 后者的签名是全新的，
