Scientific paper

We have evaluated the likely progenitor masses MPG of nebulae having elliptical, circular and bipolar morphologies, using observed ratios between the populations of these sources, and deduced central star mass functions. We find that most bipolar nebulae (BPNe) are likely to arise from progenitors having mass MPG>2.3Msolar and spectral types earlier than A3.2, whilst circular sources are associated with progenitors of mass 1.0Msolar
