Resumen:
The existence of dust around hot, massive and luminous objects, as B[e]
supergiants, is still not well understood. One possible scenario is linked
to the presence of a high density and low expansion velocity equatorial
disk, which would harbour neutral and low ionized gas and dust. However,
the formation of a stable disk is physically challenging. A possible answer
would be the detection and channeling of the mass ejected towards the equatorial
plane of the supergiant by a faint companion. In this work, we present VLTI/MIDI
high angular resolution observations and GEMINI/PHOENIX infrared spectra to
describe the gas and dust environments around the galactic B[e] supergiant
HD 327083, which is suspected to have a F-type companion.
