  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 atomic clocks. If the dark sector
connects to the standard model sector via a Higgs or photon 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
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.
