The inner coma of 67P/Churyumov-Gerasimenko as seen from OSIRIS and VIRTIS on board Rosetta
Abstract
On 27 April 2015, VIRTIS-M and OSIRIS on board Rosetta monitored the inner coma of 67P/Churyumov-Gerasimenko, observing the evolving dust and gas during a complete comet rotation. We have analyzed the diurnal behavior of the dust at about 630 nm. We also studied the evolution of the emission due to CO2 at 4200 nm and water vapor at 2700 nm over the comet day, and we compared the observed water production rate with the one computed by a thermo-physical model. The diurnal variations of dust, H2O and CO2 will be presented, compared and discussed.
