Scientific paper

The results of infrared observations of SN 1987A are reported. All the lines are broad, with typical FWHM of 3000 km/s. The findings for the lines of H, He, Fe, neutral atoms, and CO are discussed. The spectrum is dominated by emission lines from a gas of low ionization degree and apparently relatively normal abundances. The symmetry and widths of the lines are generally consistent with an envelope expanding at 1000-2000 km/s. However, the emission in virtually all lines appears to be dominated by a gas receding along the line of sight at a few hundreds of km/s relative to the systemic velocity of the LMC.
