Disk-Driven Planetary Nebulae: Shapes and Spectra

Key Points

• Disk-driven outflows resemble known cylindrical nebulae, showcasing distinctive shapes.
• Synthetic spectra analysis indicates a 'Hubble' type outflow present in certain calculations.
• Numerical hydrodynamics were employed to model the physical processes driving these outflows.
• The findings suggest that the structures of these nebulae are influenced by the dynamics around a luminous central star.
