Comet 12P/Pons-Brooks and its meteor showers

ABSTRAKT / ABSTRACT :

We investigated the evolution of the theoretical
stream originating from the comet 12P/Pons-Brooks to understand
its meteor-shower complex in more detail.
We model a theoretical comet stream assuming an ejection of
10 000 particles, representing the meteoroids, from its nucleus
in several past perihelion passages.
Two nighttime and two daytime showers are predicted to originate from 12P.
The shower predicted to have the most particles is the nighttime shower,
which can clearly be identified to the December κ-Draconids, No. 336 in
the IAU MDC list. Another predicted nighttime shower has no counterpart
in the considered observational data. Some characteristics of this shower
are vaguely similar to those of Northern June Aquilids, No. 164. The
observed counterparts of two predicted daytime showers were not found
in the observational data we used or in the IAU MDC list.
