V838 Mon: an L supergiant?
Abstract
We present a 0.8-2.5 μm spectrum of the peculiar variable V838 Mon, obtained on 2002 October 29. We see one of the coolest stars - certainly the coolest supergiant - ever observed, with deep water bands and other spectral signatures normally associated with very late L and T brown dwarfs. We suggest that V838 Mon may be the first known `L supergiant'.
