1988ApJ...331L...9E LINE IDENTIFICATIONS IN THE INFRARED SPECTRUM OF SN 1987A J. H. ELIAS, B. GREGORY, M. M. PHILLIPS, AND R. E. WILLIAMS Cerro Tololo Inter-American Observatory, National Optical Astronomy Observatories JAMES R. GRAHAM Department of Physics, California Institute of Technology W. P. S. MEIKLE Imperial College, London AND R. D. SCHWARTZ AND B. WILKING University of Missouri, St. Louis Received 1988 February 29; accepted 1988 May 2 ABSTRACT Infrared spectra of SN 1987A in the LMC from 0.9 to 4 microns are presented for the first 180 days after outburst, along with limited 1-20 micron broad-band photometry. During this period the spectrum showed P Cygni profiles superposed on a reasonably well-defined continuum, although the latest spectra show increasing structure in the continuum. Line identifications are generally consistent with expectations based on visible-wavelength spectra: lines of H I, He I, Sr II, C I, and Si I. CO may also be present in emission. Subject headings: infrared: spectra - line identifications - stars: supernovae
