Ikeya-Zhang e Hale-Bopp: due comete a confronto; Ikeya-Zhang e Hale-Bopp: due comete a confronto
Abstract
We identified four main morphological structures near the nuclear region of the comet Ikeya-Zhang (I-Z): halons, jets, shells and spirals. Their physical interpretation was derived from a comparison with similar structures found in the comet Hale-Bopp. This work enabled us to deduce some important dynamical parameters of I-Z nucleus.
