Abstract:
    The nature of embedded accretion disks around forming high-mass stars
    is one of the missing puzzle pieces for a general understanding of the
    formation of the most massive and luminous stars.

    We want to dissect the small-scale structure of the dust continuum and
    kinematic gas emission toward two of the most prominent high-mass disk
    candidates.

Description:
    Using the Plateau de Bure Interferometer at ∼1.36mm wavelengths in
    its most extended configuration we probe the dust and gas emission at
    ∼0.3" , corresponding to linear resolution elements of ∼800AU.
