Infrared Spectroscopy of V4334 Sgr (Sakurai's Object)

IR spectroscopy and photometry in the 0.8–2.4 and 3–14 μm regions are reported for seven dates between March 21 1998 and July 20 2000 UT. The shorter wavelength region displays a smooth continuum increasing to longer wavelengths that is indicative of the Wien tail of a Planck function. Only theHe I 1.0830 line is present early and it shows a P-Cygni profile which later disappears. The long wave spectra show a smooth continuum between 3 and 13μm that was well fit by a gray body at 1000 K. A weak, unidentified emission feature appears between 8 and 10 μm
