Planetary Nebulae & White Dwarfs: Physical Mechanisms

Planetary nebulae are glowing shells of gas expelled by dying low- and intermediate-mass stars, while white dwarfs are the compact stellar cores left behind. These systems trace late stellar mass loss, chemical enrichment, compact-matter physics, distance scales, and binary evolution leading to novae or some Type Ia supernovae.
