(J004444.52+412804.0)

This object was first proposed to be a P Cyg-type LBV candidate [95]. With the detection of [Ca II] emission and circumstellar dust [98], and with the determination of an effective temperature of 6600 K [142], it was classified as a warm hypergiant. On the other hand, a B[e]SG classification with a central star of 15,000–20,000 K has been suggested, based on the presence of He I lines displaying P Cyg profiles and the detection of intense CO band emission [137]. This controversial classification, based on spectra taken at similar epochs, requires clarification. Infrared photometry places J004444.52+412804.0 within the region occupied by B[e]SGs in the two color–color diagrams.
