    Abstract

    Circumstellar disks play an important role in many stages of the
    evolution of stars. However, it is only possible to directly image circumstellar
    disks for a few of the nearest stars. For massive stars, the situation is even
    more di±cult, as they are on average further away than the more numerous low
    mass stars. In order to shed light on such disks we are pursuing a programme of
    spectropolarimetry. This technique can reveal the presence of disks on a spatial
    scale of order stellar radii, while it has the potential for further modeling. Here
    we present our results on two groups of stars, on young, intermediate mass, premain sequence Herbig Ae/Be stars and on a sample of massive evolved objects,
    the Luminous Blue Variables. We also present initial results obtained at nearinfrared
    wavelengths.
