Comments on review by Harris

Abstract

Harris (1993) in his review of the paper on Corvid meteoroids by Hartung (1993) questions the validity of the latter's analysis of possible commensurability relationships involving the periods of the heliocentric orbits of the earth-moon system and possible Giordano Bruno impact-derived Corvid meteoroids. Harris establishes upper limits for dispersion velocities by considering three regimes. His argument is that these maximum dispersion velocities are so low that their natural occurrence is implausible. Hartung infers that there may exist a permitted class of orbits which have periods longer than 1.02 yr and which once were filled with large ejected masses with dispersion velocities high enough to satisfy Harris' plausibility criterion, but not so high as to exceed his maximum acceptable dispersion velocities given in the lower curve he adduces.
