(VFTS 698)

This is the third object identified within in the VLT-FLAMES Tarantula Survey and suggested as B[e]SG [119]. It also lacks a red optical spectrum to ascertain the presence of [O I] emission in order to be considered a B[e] star. Its spectral variability and photometric light curve unveiled that the object is most likely an interacting binary consisting possibly of an early B-type star and a veiled more massive companion. Its IR colors place it in both diagrams into the region occupied by HAeBe stars, but the luminosity estimates for both stars with log *L*/*L* ∼ 5 and 5.3 are too high for a pre-main sequence classification. Correcting for the extinction towards VFTS 698 would shift the object closer to the LBV domain. In the WISE diagram, the object appears particularly far off from the location of the classical B[e]SGs. Hence, this object needs further investigations for a proper classification.
