Chameleon dark matter stars    [PDF]

Vladimir Folomeev, Ascar Aringazin, Vladimir Dzhunushaliev
We consider static, spherically symmetric equilibrium configurations consisting of interacting dark matter/dark energy and embedded in an external, homogeneous chameleon scalar field. With the coupling function, form of which is taken to meet cosmological observations, we estimate the effect of such a nonminimal coupling on the properties of dark matter compact configurations. We show that the masses and sizes of the resulting chameleon dark matter stars are smaller than those of systems with no field present.
