Effective accelerations in the dust tail of comet Bennett /1970 II/
Abstract
Structural changes in comet Bennett observed in April 1970 are described. Values of the effective acceleration acting on particles in the comet's dust tail are determined. The limiting values of the repulsive acceleration obtained for the envelopes of the type II dust tail are shown to indicate a significant particle size dispersion for the dust component of the cometary atmosphere. The temporal variation of the repulsive acceleration is taken as evidence for a time-dependent process of dust formation.
