Celestial objects as strongly-interacting nonannihilating dark matter detectors

Nonannihilating dark matter particles, owing to their interactions with ordinary baryonic matter, can efficiently accumulate inside celestial objects. For heavy mass, they gravitate toward the core of the celestial objects, thermalize in a small core region, and eventually form tiny black holes via core collapse, resulting destruction of the host objects. We demonstrate that the existence of a variety of celestial objects provides stringent constraints on strongly interacting heavy dark matter, a blind spot for the terrestrial dark matter detectors as well as for the cosmological probes. Celestial objects with larger sizes and lower core temperatures, such as Jupiter, are the most optimal detectors to probe the strongly interacting heavy nonannihilating dark matter.

Automated summary

Nonannihilating dark matter particles can efficiently accumulate inside celestial objects due to their interactions with ordinary baryonic matter. For heavy mass, these particles gravitate towards the core, thermalize, and eventually form tiny black holes, leading to the destruction of the host objects. The existence of various celestial objects provides strong constraints on strongly interacting heavy dark matter, which cannot be detected by terrestrial detectors or cosmological probes. Celestial objects with larger sizes and lower core temperatures, such as Jupiter, are optimal detectors to probe strongly interacting heavy nonannihilating dark matter.
