Independent identification of meteor showers from the EDMOND and the search for their parent bodies

Abstract

Meteor shower identification and search for parent bodies of the meteoroid streams are still on-going topics of meteor science. Both problems are often approached by comparing the orbital (and/or geocentric) parameters of the investigated bodies, as is done in the independent identification method developed by Rudawska et al. (2014). In our work we applied the slightly modified version of the method to 3 most numerous years of the EDMOND (The European viDeo MeteOr Network Database) meteor data, and identified 517 meteor showers. Found showers were characterized and the problematic cases of mis-identification and hyperbolic orbits were analysed. The newly determined mean orbital parameters were then compared with known cometary and NEO (near-Earth object) orbits with the goal to get a broader picture of the associations of known and also suggested parent bodies of the meteoroid streams. From our results, 62 of known associations with the parent bodies were confirmed, and 13 new parent comets were proposed. For 7 meteor showers, new seemingly better solutions among the shower-asteroid associations are suggested.
