AMBER high-spectral resolution interferometry of Be stars: More than   just stars and disks?
  High spectral-resolution Br-gamma VLTI/AMBER observations of classical Be stars reveal complex visibility, phase, and closure phase profiles, which were not seen in previous lower-resolution data. They present new challenges for the modeling of Be stars and may require additional ingredients over and above the conventional central star + circumstellar disk paradigm.
