Scientific paper

The fluid-dynamic approach to dust tails of comets introduced by Finson and Probstein (1968) is extended to an approximation of the rigorous three-dimensional model of dust tails established by Kimura and Liu (1977), by considering the tail as composed of ellipsoidal dust shells instead of spherical ones. Following these improvements, the inverse approach to the Finson-Probstein method (Fulle, 1987) can be applied to the dust tail and anti-tail of comet Arend-Roland 1957 III and to the dust tail of comet Seki-Lines 1962 III. The outbursts of the dust number production rate can be explained by the fragmentation processes of large dust, and/or by the interruption of accretion processes of small dust, during the bursts. Even if these two comets had an hyperbolic orbit, they would inject meteoroids into the Solar System. The dust mass injected into bounded orbits is (0.3 - 50)×1012g for comet Arend-Roland and (3 - 5)×1012g for comet Seki-Lines.
