Abstract

The existence of dust around hot, massive and luminous objects, such 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 harbor 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.
