Nalin SamarasinhaNASA Planetary Mission Data AnalysisModeling Coma Morphologies of Comets 9P/Tempel 1 and 19P/Borrelly: Placing Spacecraft Data Into Context
Detailed numerical modeling of the near-nucleus comae of comets 9P/Tempel 1 and 19P/Borrelly observed by two NASA spacecraft are proposed. The modeling will be carried out with existing Monte Carlo codes (or with appropriate minor modifications to them). The spacecraft data will be complemented by additional data in the NASA Planetary Data System and in the literature.
The proposed investigation will provide contexts to the dust and gas images of comet 9P/Tempel 1 from the Deep Impact spacecraft and to the dust images of 19P/Borrelly from the Deep Space 1 mission. The outflow velocities of the coma features will be derived and the radiation pressure effects on the dust will be characterized. For gas images of comet 9P/Tempel 1, an assessment will be made of the effectiveness of the Haser model for deriving the production rates.
This work will enhance the scientific return of NASA missions to two Jupiter-family comets with disparate chemical compositions. The results for comet 9P/Tempel 1 will be conveyed to the Stardust NExT mission team.
