Abstract. We study the effects on the linear polarization in the visible continuum spectrum produced by circunstellar Be star discs with scale heights larger than the allowed for by the Keplerian discs. We consider non isothermal discs with different geometry and density distributions and calculate the linear polarization by means of multiscattering Monte Carlo simulations. Our results show that discs with large scale heights in regions close to the central star cannot be excluded as they reproduced a polarization consistent with the observations.
