Query: Cometary science with CUBES   The proposed CUBES spectrograph for ESO's Very Large Telescope will be an
exceptionally powerful instrument for the study of comets. The gas coma of a
comet contains a large number of emission features in the near-UV range covered
by CUBES (305-400 nm), which are diagnostic of the composition of the ices in
its nucleus and the chemistry in the coma. Production rates and relative ratios
between different species reveal how much ice is present and inform models of
the conditions in the early solar system. In particular, CUBES will lead to
advances in detection of water from very faint comets, revealing how much ice
may be hidden in the main asteroid belt, and in measuring isotopic and
molecular composition ratios in a much wider range of comets than currently
possible, provide constraints on their formation temperatures. CUBES will also
be sensitive to emissions from gaseous metals (e.g., FeI and NiI), which have
recently been identified in comets and offer an entirely new area of
investigation to understand these enigmatic objects.
