                         task of re-studying the interaction of the solar wind with the 
                         comets ionosphere through the Biermann et alii model. First, exact 
                         solutions for the number density of the neutral particles 
                         outgassing from the comets nucleus, in the presence of the solar 
                         radiation pressure, are obtained. This kind of information is 
                         extremely important in the formation of the shock wave and 
                         tangential discontinuity, on the sunside of the comet, after the 
                         neutrals become ionized. Next, solutions of the conservation 
                         equation of the number density, mass, momentum and energy, are 
                         obtained. In order to compare the results of the integrations, 
                         with those obtained by Biermann et alii, the equations proposed by 
                         these authors are also solved. The results obtained lead to a very 
                         dense cometary ionosphere and, hence, the theoretical predictions 
                         become even more different from the experimental observations. It 
                         is concluded that a more elaborated model than the Biermann et 
                         alii is necessary in order to get satisfactory results.",
