| Abstract: | We explored the substantial spatial spread of the Quadrantid stream, based on the backward integration of orbital motions
of the Quadrantids, impulsively perturbed by Jupiter. We found that the Jovian impulses can widely spread out them in the
early twentieth century, especially their perihelia extended by a factor of ∼90 than those at the observed epoch. We regarded
the spread as the intrinsic one of the Quadrantid stream itself. |
