Quadrantids filaments modeling

TL;DR

This study models the long-term dynamical evolution of the Quadrantid meteor stream, revealing its complex behavior, limited lifespan of filaments, and suggesting multistage particle ejection over different epochs.

Contribution

It provides a detailed orbital integration analysis over 20,000 years, identifying stable and unstable filaments and proposing a multistage ejection model for the stream.

Findings

Approximately 20% of particles escape the stream within 5,000 years.

Only four filaments are older than 500 years and remain observable.

Filament dynamics suggest multiple ejection epochs for stream particles.

Abstract

Numeric integration of orbits of particles along mean orbit of Quadrantid meteor stream is done at time span 20000 years. Orbits are subdivided on several classes by their evolution type. A very complex dynamical behavior is detected. About 20% of modeled particles escape stream: this fact point on that stream cannot be long-live and have a source within 5000 years. After that, Quadrantid filaments dynamics are studied. By comparison of different authors data, 7 independent filaments are selected. Only four of them can have age more than 500 year. Others are unstable or have a small age. Only few Quadrantid filaments can be continuous and observable at all longitudes. Other filaments consist of separate clumps, which occurs number of meteor phenomenon in separate years and non active at different epoch. A complex view of filament dynamical evolution argues in favor multistage ejection particles into a stream at different epoch.
