2D spectroscopy of planetary nebulae with high abundance discrepancies
The discrepancy between chemical abundances calculated from optical recombination lines (RLs) and collisional excitation lines (CELs) is an important unsolved problem in nebular astrophysics. In planetary nebulae (PNe) there is increasing evidence that the discrepancy is due to the presence of two gas phases: a hot component with standard
