Modeling the physical and excitation conditions of the molecular envelope of NGC 7027
The link between the shaping of bipolar planetary nebulae and the mass ejection activity of their central stars is still poorly understood. Appropriately characterizing the evolution of the shells ejected during the late stages of evolution is vital to gain insight into the mechanism of nebular shaping. Herschel/HIFI provides an …
