Using adaptive optics at the Gemini North telescope we have obtained a K-bandspectrum of the star near the center of the luminous Galactic center bowshockIRS8, as well as a spectrum of the bowshock itself. The stellar spectrumcontains emission and absorption lines characteristic of an O5-O6 giant orsupergiant. The wind from such a star is fully capable of producing theobserved bowshock. However, both the early spectral type and the apparentlyyoung age of the star, if it is single, mark it as unique among hot starswithin one parsec of the center.Comment: 17 pages incl. 4 figures, to be published in ApJ 10 Nov. 200
