we propose observations of the heavy-element interior of supernova sn1987a utilizing the nii (7.51 microns), niii (6.64 microns), fei (24.04, 34.71 and 51.29 microns), feii (25.99, 35.34 and 51.68 microns), and feiii (22.93, 33.04 and 54.31 microns) lines. these measurements are a followon to our successful iron and nickel line studies from the kuiper airborne observatory (erickson etal. 1988; haas etal. 1990; wooden etal. 1993; colgan etal. 1994). utilizing the increased sensitivity of iso, we will continue to probe the evolution of the ionization states, densities, and temperatures of the iron-rich regions of the ejecta, and ascertain the existence of a central energy source (i.e. a pulsar).

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
