MEASUREMENTS of the strength of permitted spectral lines from neutral oxygen in comets should provide both a better understanding of gas dynamics in comets and an assessment of whether the production ratio of oxygen to hydrogen in comet atmospheres is close to a half. If this ratio is confirmed, it would provide strong support for the growing evidence1that the ‘parent’ molecules which make up the solid comet nucleus are dominantly H2O. |
