We study the thermal properties of impurities embedded in a repulsive Bose gas under a harmonic trapping potential. In order to obtain the exact structural properties in this inhomogeneous many-body system, we resort to the path-integral Monte Carlo method. We find that, at low temperatures, a single impurity is expelled to the edges of the bath cloud if the impurity-boson coupling constant is larger than the boson-boson one.
