Meteor Showers and Their Parent Comets
They showed that ejection could have occurred as recently as 1500 years ago.8
They also found that the Quadrantid meteoroids might be moving in chaotic orbits
, a phenomenon associated with overlapping mean-motion resonances.

This position is located in an empty portion of northeastern Bootes some 20°E of
the second-magnitude star Alkaid (eta Ursae Majoris). The nearest bright star is
third-magnitude beta Bootis, lying 8° to the southwest of the Quadrantid radiant.

Icy Bodies of the Solar System (IAU S263)
We have modeled the observed light curves and decelerations of Geminid and
Quadrantid meteors and studied their spectra. In both cases, we have found
typical bulk densities of about 2600 kg m-3, much larger than in cometary
meteoroids.

Advances in Meteoroid and Meteor Science
The orbits E and J mean those of Earth and Jupiter, respectively Although the
secular perturbation also advances the orbital evolution of the Quad- rantids, the
IPQs in the early twentieth century would still remain in near-Quadrantid
evolutional ...

Solid Particles in the Solar System
The Quadrantid stream is much younger and is affected by strong Jovian
perturbations giving rise to irregular changes in its activity. The Poynting-
Robertson effect appears to deplete the smaller meteoroids from a stream so that
old streams ...
I. Halliday, B.A. McIntosh, 1980
But according to my own rough estimation, time for full revolution of the node for
the Quadrantid stream is about 16 thousand years. At the same conference!
