Scientific paper

In their previous paper (1983) the authors found analytical expressions for the distance along the meteor trajectory as a function of time. In the present paper they did not restrict themselves to the assumption of an exponential air density profile and they succeeded in finding a general solution for an arbitrary atmosphere. They applied the resulting formulae to two fireballs with good dynamic data. The assumption of an extremely simple atmospheric model for deep-penetrating fireballs yields, incorrectly, greater values of ablation coefficients, smaller initial velocities and smaller bulk densities of meteroids. The air density profile of the instantaneous atmosphere must be used for any future work.
