Scientific paper

The photometrical dust tail data on the antitails of the short-period comets P/Encke and P/D'Arrest published by Sekanina and Schuster (1978) are analyzed using the new inverse numerical approach of Fulle (1989). For P/Encke, a total mass of meteoroids of (5 + or - 1) x 10 to the 12th g and a power index of the time-averaged size distribution of -3.6 + or - 0.3 are obtained. For P/D'Arrest, the corresponding values are (8 + or - 2) x 10 to the 12th g and -3.8 + or - 0.1. These results show that Sekanina and Schuster underestimated the number of ejected large grains, due to their unrealistic hypothesis of dust ejection at zero velocity. Ejection velocities are reported here which imply that dust shells cover almost the whole isophote fields. It is also shown that a short-period comet injects into the zodiacal cloud a meteoroid input mass rate of at least 30,000-50,000 g/s, so that the contribution of all short-period comets may balance the losses of the interplanetary dust cloud.
