Scientific paper

We propose to use HRS observations of a suitable target-of-opportunity comet to study two outstanding problems related to the composition of the volatile component of the cometary nucleus. These problems concern two species, CO and S2, which have been observed in the cometary coma and identified as "parent" molecules sublimating directly from the nucleus. Both of these molecules have their principal fluorescent emissions in the vaccuum ultraviolet. The high spectral resolution will allow the determination of the rotational temperature of CO, which is diagnostic of the source temperature and the excitation mechanism of the observed emission. The determination of the abundance of both CO and S2 in the primarily water ice of the nucleus can serve to constrain current models of comet formation in the primordial solar nebula.
