Parent comets of IAU MDC meteoroid streams unaltered by dynamical evolution

ABSTRACT Meteoroids that are members of a meteoroid stream move around the Sun in the mutually similar orbits, and their mean orbit is also similar to the orbit of the parent body, at least in the first stage of their dynamical evolution. This similarity enables the identification of the parent body of the stream. We evaluated the similarity of the meteoroid streams’ mean orbits from the IAU Meteor Data Center data base and all-known orbits of comets in course to find further, not-yet-known associations between meteor showers and their parent comets. We found 81 new associations and confirmed 84 associations that were discovered by other authors in the past.
