The radial distribution of dust has been calculated in outflows driven byradiation pressure in which the gas drag is taken into account. It is shownthat the dust distribution in the newly discovered candidate disk aroundBD+31d643 can be explained by this simple model, provided that the ambient gasof the surrounding cluster IC 348 has a density $\rho\sim 10^4~$cm$^{-3}$. Thedust is probably produced within 2300 AU from the central binary star.
