Periodic Variability of the Central Stars of Planetary Nebulae Surveyed through the Zwicky Transient Facility

Pinjian Chen, Xuan Fang, Xiaodian Chen +1

A consensus has been reached in recent years that binarity plays an important role in the formation and evolution of a significant fraction of planetary nebulae (PNe). Utilizing th…
