Abundance measurements of 67P/Churyumov Gerasimenko main volatile species

Abstract.
Comets considered to be pristine objects contain key information about the early formation of the Solar System. Their volatile components can provide clues about the origin and evolution of gases and ices in the comets. Measurements with ROSINA/RTOF at 67P/Churyumov–Gerasimenko have now allowed for the first time a direct in-situ high-time resolution measurement of the most abundant cometary molecules originating directly from a comet’s nucleus over a long time-period, much longer than any previous measurements at a close distance to a comet. We determined the local densities of H2O, CO2 and CO and investigate their variabilities.
