摘要： With a combination of the Direct Simulation Monte Carlo (DSMC) calculation and test particle computation, the ballistic transport process of the hydroxyl radicals and oxygen atoms produced by photodissociation of water molecules in the coma of comet 67P/Churyumov–Gerasimenko is modelled. We discuss the key elements and essential features of such simulations which results can be compared with the remote-sensing and in situ measurements of cometary gas coma from the Rosetta mission at different orbital phases of this comet. 其他題名： Earth Moon Planets 出版者： Dordrecht: Springer Netherlands 出版日期： 2016-03-01 出處： Discover Space, 2016-03, Vol.117 (1), p.23-39 版權： Springer Science+Business Media Dordrecht 2016 版權： Springer Science+Business Media Dordrecht 2016. 版權： Copyright Springer Nature B.V.
