How is the coma of a comet produced
Web9 apr. 2024 · An important merit of the Euler equations is that they don`t depend on the flow rarefaction and therefore the solutions can be scaled for different production rates, the main reason why the authors use them in the present model. – It is assumed that the dust does not influence the gas flow (i.e. no back-coupling of the dust to the gas flow). how: WebThe Coma of Comet 2P/Encke Paul D. Feldman ([email protected]) Department of Physics and Astronomy, The Johns Hopkins University, ... have continued to provide information about the water production rates of many comets, both short-period comets such as Encke, as well as for comets entering the inner solar system for the first time.

WebFor a comet near the orbit of Earth, this is about 1 km/s. This speed and the lifetime of molecules to photo-destruction together determine the scale of the cometary coma. In one day, at 1 km/s, the molecules in the coma can travel about 50,000 km and this is the approximate radius of the gas coma.
