Abstract (from CDS):
R. W. Russell, R. J. Rudy, D. K. Lynch, S. Mazuk, and R. L. Pearson, The Aerospace Corporation; C. E. Woodward, University of Minnesota; R. C. Puetter, Center for Astrophysics and Space Science, University of California at San Diego; and R. B. Perry, Langley Research Center, NASA, report 0.4- to 2.5-micron spectroscopy of this nova (cf. IAUC 8810, 8812) using the Lick 3-m telescope (+ VNIRIS) on May 6 UT, as well as 0.8- to 5.5-micron spectroscopy using the Infrared Telescope Facility (IRTF) 3-m telescope (+ SpeX) on May 31. This object has faded considerably over the past month, but the character of its rather complex spectrum has not changed significantly. The spectrum has broad and clearly doubled lines and is dominated by He I emission features. O I is still present, and the forbidden lines [O II], [O III], and [N II] are present. There are no indications of coronal lines or dust formation. The interstellar reddening derived from the O I lines is E(B-V) = 0.7.
