Description
Although massive stars die in brilliant and brief conflagrations, their lower-mass cousins lose their outer layers in dense winds over thousands of years and far more ‘thoughtfully’. Until recently the evolution of these Planetary Nebulae appeared to be well understood. Two decades of new results, mostly from HST, have posed new sets of new challenges at about the same rate that theoretical simulations have been able to provide insights. In this survey talk I will provide an overview of what we know and what we are yet to understand about the twists and turns along the glide path to white dwarfdom.
