Regions around the wavelength of the HeI line at 1.700 μm (top) and of the Brackett gamma line at 2.166 μm (bottom). Top: Prominence of the HeI line, together with the absence of the neighbouring HeII line at 1.693 μm and the absence of the Brackett 11 line at 1.681 μm, leads us to classify it as a very early B star, presumable a B0.5e spectral type. Bottom: Brackett gamma line clearly shows a core in emission.
