SA: Formation and Evolution of central stars of Planetary Nebulae – Miller Bertolami

April 18 @ 11:15 am 12:00 pm CMT

Since their discovery in 1764 our ideas for the formation of Planetary Nebulae (PNe) have improved continuously. The basic picture traced in the mid-twentieth century of PNe being transition objects between the giant branch century of PNe being transition objects between the giant branch and the final white dwarf stage has been enriched by the discovery of strong axisymmetric PNe and the realization in the last decades that completely isolated star might not be able to form these structure. Additionally, the discovery that many solar-like stars have planetary companions or are in binary systems suggests that stellar and sub-stellar companions likely play a role in either the formation or the shaping of axisymmetric PNe. In this presentation, I will review our current understanding of the formation of PNe and the evolutionary channels that give rise to the wide diversity of central stars and PNe.
