Poeckert, R. ; Marlborough, J. M. Abstract The polarization of 48 Be stars has been measured in two bands near Ha with the aim of determining the relation between intrinsic polarization and V sin i. A technique developed by Poeckert (1975) is used to remove the effect of interstellar polarization. It is found that intrinsic polarization depends strongly on V sin i: stars with low V sin i have little or no polarization. No apparent difference between pole-on and extreme Be stars was obtained. A comparison of the observed relation between the intrinsic polarization and V sin i, and that predicted for an optically thin disk viewed at varying angle i is illustrated, and it is found that an envelope with an electron density of < 5 x 1011 can account for the degree of intrinsic polarization observed in all the program stars.
