Query: No-hair theorems for a static and stationary reflecting star   We prove the non existence of massive scalar, vector and tensor hairs outside
the surface of a static and stationary compact reflecting star. Our result is
the extension of the no hair theorem for black holes to horizonless compact
configurations with reflecting boundary condition at the surface. We also
generalize the proof for spacetimes with a positive cosmological constant.
