Summary We studied a spherically symmetric dense object in soft-wall model. We try to improve the studies in hard-wall model by removing the ambiguity at IR-boundary. The density profile obtained from soft-wall model is not so bad until A<30, however it does not have much plateau. 11/11Feb 21-24, 2011, HNP2011
