Dynamical modeling validation of parent bodies associated with newly discovered CMN meteor showers

TL;DR

This study validates potential parent bodies of newly discovered CMN meteor showers through dynamical modeling, confirming some connections with comets and asteroids, while others remain inconclusive or require more data.

Contribution

It introduces a method combining particle ejection simulations and dynamical modeling to verify meteor shower-parent body associations.

Findings

3 showers linked to comets

4 showers linked to asteroids/dormant comets

2 cases require further observation

Abstract

Context: Results from previous searches for new meteor showers in the combined Croatian Meteor Network and SonotaCo meteor databases suggested possible parent bodies for several newly identified showers. Aims: We aim to perform an analysis to validate the connection between the identified showers and candidate parent bodies. Methods: Simulated particles were ejected from candidate parent bodies, a dynamical modeling was performed and the results were compared to the real meteor shower observations. Results: From the 13 analysed cases, three were found to be connected with comets, four with asteroids which are possibly dormant comets, four were inconclusive or negative, and two need more observational data before any conclusions can be drawn.
