Abstract
We report high-resolution (25) CO J = 1-0 line imaging that confirms the presence of a molecular disk around the origin of the spectacular, 14'×4', episodic jets in the planetary nebula KjPn 8. The disk is 30'' in diameter, with an expansion velocity of ≈ 7 km s-1. The axis of the disk is aligned with the youngest and fastest (≈ 300 km s−1) of the bipolar jets, and there is evidence for interaction between the jets and the disk material. The inner 4'' of the disk are photoionized by the central star. The disk-jet system dominates the environment of this young nebula and should govern the morphology of KjPn 8 as it evolves to become fully ionized.
