Orbital evolution under the action of fast interstellar gas flow.
PASTOR P., KLACKA J. and KOMAR L.
Abstract (from CDS):
We study the evolution of a putative dust ring in the zone of the Edgeworth–Kuiper belt. The non-radial solar wind and the gravitational effect of the major planets might have an important role in this zone. We take into account both these effects. The low-inclination orbits of micrometre-sized dust particles in the belt are not stable, because of the fast increase of eccentricity caused by the long-term monodirectional interstellar gas flow and subsequent planetary perturbations – the increase of eccentricity leads to the planet-crossing orbits of the particles.
Gravitational and non-gravitational effects are treated in a way that fully respects physics. As a consequence, some of the published results have turned out to be incorrect. Moreover, in this paper we treat the problem in a more general way than it has been presented up to now.
The influence of the fast interstellar neutral gas flow should not be ignored in the modelling of the evolution of dust particles beyond planets.
