A Planetary Nebula from a 5.7 M⊙ Progenitor in a 90 Myr M31 Star Cluster

Planetary nebulae (PNe) trace the late evolution of low-to-intermediate-mass stars, yet the masses of their progenitors are rarely measured directly. Here we present a PN physically associated with a young star cluster in M31, providing an unprecedented extragalactic empirical anchor in the poorly c...
