TL;DR
This study analyzes the Taurid meteor stream, revealing it as a reservoir of large impactors with a complex size distribution, orbital characteristics, and recent fragmentation activity, enhancing understanding of its origin and evolution.
Contribution
First precise observations of the Taurid stream in 2015, establishing its size distribution, orbital properties, and recent fragmentation history, suggesting ongoing evolution of a cometary complex.
Findings
Stream dominated by larger meteoroids with a gentle collisional fragmentation signature.
Meteoroids have orbital periods near the 7:2 resonance with Jupiter.
Recent activity from fragmentation involving asteroid 2015TX24 supports a long-term breakup model.
Abstract
The Desert Fireball Network observed a significant outburst of fireballs belonging to the Southern Taurid Complex of meteor showers between October 27 and November 17, 2015. At the same time, the Cameras for Allsky Meteor Surveillance project detected a distinct population of smaller meteors belonging to the irregular IAU shower #628, the s-Taurids. While this returning outburst was predicted and observed in previous work, the reason for this stream is not yet understood. 2015 was the first year that the stream was precisely observed, providing an opportunity to better understand its nature. We analyse the orbital elements of stream members, and establish a size frequency distribution from millimetre to metre size range. The stream is highly stratified with a large change of entry speed along Earth's orbit. We confirm that the meteoroids have orbital periods near the 7:2 mean-motion…
