Infrared observations of SN 1987A : probing the ejecta and its surrounding medium.
Abstract
IR observations of the ejecta from SN 1987A are reviewed. The structure lines of heavy elements in the ejectra are discussed, including the discovery of the presence of CO and SiO molecules in the supernova spectrum. Observations of the ambient medium are noted and the mass and distribution of dust in the circumstellar shell are examined. Also, consideration is given to the possible presence of IR arcs around SN 1987A.
