Evidence for a Binary origin of the Young Planetary Nebula HB 12 [PDF]
arXiv, 2006 Young planetary nebulae play an important role in stellar evolution when intermediate- to low-mass stars (0.8 ~ 8 M) evolve from the proto-planetary nebulae phase to the planetary nebulae phase. Many young planetary nebulae display distinct bipolar structures as they evolve away from the proto-planetary nebulae phase.

A Dust-Scattering Model for M1-92: A Revised Estimate of the Mass Distribution and Inclination
GalaxiesPreplanetary nebulae (PPNe) are formed from mass-ejecting late-stage AGB stars. Much of the light from the star gets scattered or absorbed by dust particles, giving rise to the observed reflection nebula seen at visible and near-IR wavelengths ...
