The Importance of Binaries in the Formation and Evolution of Planetary Nebulae

The book explores the significant role of binary evolutionary pathways in the formation of planetary nebulae, suggesting that binarity may be essential for observable nebulae. It builds on previous research to present a comprehensive overview of theoretical and observational evidence supporting this idea. The discussion includes common envelope evolution and wider binary systems, emphasizing the broader implications for astrophysics, such as the understanding of type Ia supernovae, chemically peculiar stars, and circumbinary exoplanets.
