Query: Disk and wind interaction in the young stellar object MWC 297 spatially
  resolved with VLTI/AMBER   The young stellar object MWC 297 has been observed with the VLT
interferometer equipped with the AMBER instrument. MWC 297 has been spatially
resolved in the continuum with a visibility of 0.50 as well as in the Br gamma
emission line where the visibility decrease to a lower value of 0.33. This
change in the visibility with the wavelength can be interpreted by the presence
of an optically thick disk responsible for the visibility in the continuum and
of a stellar wind traced by Br gamma and whose apparent size is 40% larger. We
validate this interpretation by building a model of the stellar environment
that combines a geometrically thin, optically thick accretion disk model
consisting of gas and dust, and a latitude-dependent stellar wind outflowing
above the disk surface. The continuum emission and visibilities obtained from
this model are fully consistent with the interferometric AMBER data. They agree
also with existing optical, near-infrared spectra and other broad-band
near-infrared interferometric visibilities. A picture emerges in which MWC 297
is surrounded by an equatorial flat disk that is possibly still accreting and
an outflowing wind which has a much higher velocity in the polar region than at
the equator. [abridged]
