Title:
Meteor shower complexes of several long-period comets.

Author: M. Hajdukova, AISAS

Abstract:
I will introduce aspects of both the general characteristics and the specific features of the structures 
of the meteor shower complexes of several parent comets. Meteoroids in a stream are, after their ejection 
from the comet, subsequently influenced by the gravitation of planets and non-gravitational forces. 
As a result, a filamentary structure of the stream may be formed. If more than a single filament passes 
through the Earths orbit, we observe several meteor showers associated with the same parent body. The radiants 
of the associated showers often exhibit a symmetry. This presentation will cover the results of our recent 
analyses of the meteoroid streams of several comets, on which I worked together with Luboš Neslušan. 
In the last two years, we have modeled and analysed the theoretical streams of 7 long-period comets 
(C/1961 T1, C/1894 G1, C/1936 O1, C/1853 G1, C/1992 W1, C/1963 A1, C/1975 T2). We found new parent bodies 
of at least 12 minor meteor showers and 2 new meteor showers.
