Infrared Spectroscopy of V4334 Sgr (Sakurai's Object)

摘要

IR spectroscopy and photometry in the 0.8–2.4 and 3–14 μmregions are reported for seven dates between March 21 1998 and July20 2000 UT. The shorter wavelength region displays a smooth continuum increasing to longerwavelengths 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 laterdisappears. 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, unidentifiedemission feature appears between 8 and 10 μm.
