WebThe main molecular processes to produce the hydrogen comae of comets are now well known: Water, the main constituent of cometary atmospheres, is photodissociated by the solar ultraviolet radiation to form the high (20 km s -1) and low (8 km s -1) velocity components of the atomic hydrogen. 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:
