    • The binary fraction of planetary nebula central stars - III. the promise of VPHAS+ 

      Barker, Helen; Zijlstra, Albert; Marco, Orsola De; Frew, David J.; Drew, J. E.; Corradi, R. L. M.; Eislöffel, Jochen; Parker, Quentin A. (2018-04-21)
      The majority of planetary nebulae (PNe) are not spherical, and current single-star models cannot adequately explain all the morphologies we observe. This has led to the Binary Hypothesis, which states that PNe are ...

      Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, ...
