報告摘要：
Celestial bodies are well motivated laboratories for dark matter searches. I will give two such examples. In the first scenario, dark matter gets captured in the Earth by scattering with Earth nuclei. The accumulated dark matter annihilates and yields excessive heat. In the other scenario, dark photons resonantly convert to photons in the atmosphere of neutron stars or white dwarfs, producing signals in the radio frequencies that are detectable on the Earth with radio telescopes.
