Dust production of comet Halley with account of large particle contribution

Critical analysis of the results of space experiments, taking into account the contribution of large particles to the total mass production of comet Halley leads to much higher values of the dust production rate than those derived from the first analysis of space measurements. It thereby seems necessary to correct the gas-to-dust ratio of the mass production by a factor of 10, from 0.1-1.0 to 1.0-10. The corrected values of dust production rate are in much better agreement with both the current concepts of the comet's history and with the evolution of its meteor stream. (author). 20 refs
