Abstract

The variations in production rates for Comet 46P/Wirtanen for the species H2O and the parents of C2 and CN are examined from the point of view of a variety of commonly used scale lengths. The calculations are carried out as a function of heliocentric distance. It is shown that, by using a common set of scale lengths, the results of various investigators can be brought into acceptable accord. The resulting production rates of H 2O and the parents of C2 and CN versus heliocentric distance are recalculated and plotted versus the heliocentric distance r H. The curves show reasonable agreement with a slope of ∼r H-4. The water production rate near perihelion of 46P/Wirtanen is close to 2 × 1028 mol s-1.
