IAU Symposia: The lives and death-throes of massive stars

28 November – 2 December 2016
Auckland, New Zealand
 

Research on Massive Stars is undergoing a period of rapid progress. While these stars are relatively few in number they are the main driver of chemical and dynamical evolution in galaxies via their stellar winds and explosive deaths in core-collapse supernovae. Our understanding of massive stars is going through a remarkable time of change with long held convictions being shown to be incomplete. This evidence arises from new research concerning the formation and evolution of massive stars and linking this to their deaths in core-collapse supernovae. Now is a fortuitous time to make significant advances in massive star research. We propose a meeting with the central rationale to bring together the two communities that study massive stars and their supernovae.

The impact of massive stars is widely recognized in many areas. They are often used as tools to interpret the conditions and processes arising in different environments (studies of Galactic structure, chemical and dynamical feedback, population synthesis, Starbursts, high-z galaxies and cosmic reionization). In parallel, the development of new instrumentation, analysis techniques and dedicated surveys across all possible wavelengths have delivered large amounts of exquisite new data. This data is now providing a harsh test for the current state-of-the-art theoretical calculations of massive star birth, evolution and death.

Topics
- new results from large-scale surveys at different wavelengths and techniques for massive stars and supernovae
- new observational techniques and instrumentation for massive stars and supernovae
- the link between massive stars and their deaths (core-collapse and other SNe)
- short-lived phases of massive stars (LBVs, WRs and RSGs) and their characteristics as supernova progenitors
- constraints on the nucleosynthesis production in supernovae and the production of dust
- explosion mechanisms of supernovae and the parameters required for a successful explosion
- well established facts and open problems in our knowledge of massive stars
- challenges to present theoretical models: 2D and 3D models of interior and atmospheres
- massive stars as astrophysical tools: tracing the Milky Way and other galaxies structure; limits to our interpretation of the high-z Universe
