Dark Matter could potentially manifest itself in the form of asymmetric dark
stars. In this paper we entertain the possibility of probing such asymmetric
bosonic dark matter stars by the use of microwave atomic clocks. If the dark
sector connects to the bright sector via a Higgs portal, the interior of boson
stars that are in a Bose-Einstein condensate state can change the values of
physical constants that control the timing of atomic clock devices. Dilute
asymmetric dark matter boson stars passing through the Earth can induce
frequency shifts that can be observed in separated Earth based microwave atomic
clocks. This gives the opportunity to probe a class of dark matter candidates
that for the moment cannot be detected with any different conventional method.
