Abstract:
Many previous works have shown the relevance and dynamics of Jovian mean
motion resonances (MMR) in various meteoroid streams. These resonant swarms
are known to have produced spectacular meteor displays in the past. In this
work, we investigate whether any MMR due to Saturn are feasible, and
subsequently check whether such effects are strong enough to trap meteoroids
so as to cause enhanced meteor phenomena on Earth. Extensive numerical
simulations are done on two major meteoroid streams, which are known to
exhibit exterior Jovian resonances. The roles of the 1:6 and 5:14 Jovian MMR
have already been studied in the Orionids and Leonids, respectively. Now we
find strong evidence of 1:3 and 8:9 Saturnian MMR in Orionids and Leonids,
respectively. The presence of compact dust trails in real space due to these
two Saturnian resonances is confirmed from our calculations.
