Hidden Molecular Bullets in Compact Young Planetary Nebulae

For the three planetary nebulae M 1-11, Vy 2-2, and Hen 2-459, we report the detection of kinematically distinct structures that exhibit different states and mechanisms of excitation in molecular hydrogen (H _2 ). The observations were obtained with the Immersion Grating INfrared Spectrometer (or IG...
